10 Qualities of Teacup Parenting: Is Your Kid Too Fragile?

Accountability

Perhaps the most important attribute a leader needs to be successful is accountability. Humans will do amazing things if they know what is expected of them. They will often do stupid things if they don’t.

Consider the parable of the rock:

A village chieftain once asked a young warrior to bring him a rock. The young man, feeling excited, creative, and proud to have been asked, guessed  that the chieftain wanted a new decoration for his hut. He went out and found a beautiful quartz crystal and brought it to the chieftain who shrugged and said, “Thank you. But that’s not the rock I wanted. Please try again.” Disappointed, but still resolute, the warrior then decided that the chieftain must be worried about the oncoming winter, so he returned with a piece of coal. “That’s not it either,” said the chieftain. Getting frustrated, the warrior asked around the village and found that the chieftain had asked for rocks before and had once accepted a piece of granite. Thus, the young man traveled several days to a place where he could find granite. He chipped off a large piece and hauled it home to the chief, who didn’t have time to see him, but sent a message through his lieutenant-chieftain that he had changed his mind and no longer wanted a rock.

You’ve probably been on both ends of that story. I know I have. The warrior, instead of spending productive time, spent time trying to divine what the chieftain wanted. What a waste of effort! Clear instructions save everybody time and improve the quality of work. Accountability is impossible without them. You can grow leaders by giving clear instructions and letting them flourish.

I once had a manager who subscribed to the “bring me a rock” school of thought. He was a smart, talented guy, but he had very stringent, inflexible notions of how things ought to be done. He would ask me to bring him a rock over and over and over again until, at last, the rock I brought was the one he wanted. Hey, I eventually brought him what he wanted, so we succeeded together, right? Wrong. Each day seemed like a continual struggle with this manager, and I often felt like I was spinning my wheels. I definitely wasn’t as productive as I could have been. Obviously, this behavior turns people into drones whose purpose is to figure out the leader’s will.

As a leader, you have a responsibility to help your people help you. If you have particular concepts of how things ought to be done, be clear on those up front. People need a sandbox, especially in large enterprises where standards, protocol, politics, and policy, by necessity, govern. But make those boundaries as spacious and as well-documented as possible.

Once you establish boundaries, you must set people free within them. People want to feel empowered. They want to be creative. They want to solve problems and have freedom. Turn them loose and stay out of the way! People are paid to use their brains, and the more they’re micromanaged, the more they have a tendency to turn their brains off. Micromanagement can work well in very small groups with monumental challenges which require heroics. But micromanagement doesn’t grow leaders. I know. I’m a recovering micromanager and I’ve seen the negative effects of meddling on potential leaders.

It may be easy to criticize someone’s ideas. And it’s human nature to think that your way is better. You might even be prescient enough to see a potential train wreck coming. But letting leaders own their decisions allows them to feel accountable and learn from their own mistakes. We can’t (and we shouldn’t) want to teach every person to do every job. We don’t know enough and we don’t have enough time. Let people learn on their own. Each time you swoop in to solve a problem that you see coming you remove a potential lesson from the people in you organization. Accept mistakes for what they are: cheap leadership training courses.

Clear expectations and defined, yet spacious boundaries with room for mistakes will create leaders in your organization.

How To Hijack Fast Food Drive-Thru Frequencies

Disclaimer: In no way do i recommend this as it is against the law.

Definitely an interesting mod of a radio.

more video:

I can’t seem to access the site where I found this, so I’m reposting the content here.

After spending several years on Google Video and YouTube, it’s been watched approximately 20,000 times. And of those 20,000 people who have viewed it, approximately all of them have emailed me and asked me what kind of radio we used and how can they use a radio to do the same thing. So in the spirit of April 1st and in order to quell the number of emails sent to me and posts on the PLA Forums asking the same thing, I’ve decided to write this tutorial to help those people out.

But I’m not going to explain how to modify a Yaesu VX5 or a Yaesu VX7. A simple Google search will show you how to modify these ham radios. The problem with these mods is that, even though they’re fairly simple, you have to buy the radios which could cost you anywhere from $200 - $400. Then, after removing a couple solder points, you have to learn how to use it, you have to look up fast food frequency lists, you have to understand the difference between the transmit frequencies and the receive frequencies and you have to scroll through PL tones using trial and error to find the correct one.

 
Or how about we do this a different way. A way that uses a couple items that you might already have in your home. You can easily modify most old CB radios in a way that will allow them to transmit directly to drive-thru frequencies. You won’t have to scroll through hundreds of possible drive-thru frequencies, because a CB radio’s channels line up in exactly the same way as most drive-thru’s channels, only at a higher frequency. How do you get your CB radio to run at a higher frequency? A simple replacement of the crystal inside, with a 6.5536 MHz crystal. This triples the megahertz that are broadcast on and there is no learning required. You just take the modified CB radio to a fast food restaurant and start broadcasting to the customers.

“But RBCP, I don’t have a 6.5536 MHz crystal lying around my house,” you might be whining at this point. But this isn’t true. Just about any house has several 6.5536 MHz crystals in them if you know where to look. This just happens to be the exact same crystal that you can find in electric heaters, hair dryers, electric stoves, curling irons, electric hot water heaters, irons, and toasters. These crystals are in just about any item that has heated coils and are used to control the frequency of the heating elements so that they don’t burn your house down.

So for this modification you need…

1 CB radio. It has to be a 40 channel CB radio with a digital display, which includes just about any CB radio manufactured after the mid 1980’s. The old 23 channel CBs from the 1970’s will not work. It can even be a walkie talkie CB radio. If you don’t have one, you can find one at Goodwill or a yard sale for probably less than $10.

1 toaster. (Or other item with heating elements inside.) A toaster is the most ideal to use, because it’s almost guaranteed to have the crystal inside of it. It’s more common to find curling irons and hair dryers that don’t. Again, it should be a toaster manufactured within the past 20 years or so. Before that they didn’t have crystal requirements for toaster manufacturers. (And incidentally, there were a lot more electrical house fires back then.) Goodwill will probably have a toaster for less than $10.

1 soldering iron and solder. Don’t worry if you don’t have soldering experience. It’s actually pretty easy. Click here for a soldering tutorial. You can purchase a soldering iron at Radio Shack or Sears for about $10.

A few screwdrivers
Even if you have to buy all these materials, you’re only out $30. That’s a lot better than the $300 you might end up spending on a Yaesu radio. And some of you might already have all these items so you don’t have to pay anything. Ask a friend or a relative if they’ve got an old toaster or CB radio lying around that they don’t need.

First you’ll want to take apart your toaster. This isn’t too hard. Just flip it upside down and start removing the screws. You’ll probably need to pull off the plastic lever and knobs before you remove the top of the toaster. Once you have the top off, you’ll see a green or brown circuit board inside.

 
Flip the circuit board down and you’ll see all the components on the other side, including the 6.5536 MHz crystal. The crystal is silver and will have 6.5 stamped on the side of it. In the picture below, I’ve used an arrow to show you where it’s located.

 
The crystal is likely in a different spot in other toasters, but it’s hard to mistake for any other electronic component. The crystal will have some form of 6.5 stamped on the side of it. In my toaster, it showed 6.55-12. While the official frequency needed is 6.5536 MHz, anything within 1.6 megahertz will work. So don’t worry if your crystal just says 6.5 or 6.50 - it’s all the same for our purposes.

 
It’s kind of hard to see what I’m doing in the picture above, but I’m heating up the leads on the crystal from underneath with my soldering iron to melt the solder, and I’m pulling on the crystal from above with a pair of needle nose pliers. It only takes a few seconds to get the crystal out of the toaster.

 
Now that the crystal is out of your toaster, throw your toaster away! Do not attempt to use it once the crystal is removed. Remember, the crystal is in there for safety and using your toaster without the crystal could burn your toast and/or start a kitchen fire. It’s likely your toaster won’t even turn on with the missing crystal, but please don’t even try. Just throw it away.

 
As I mentioned before, just about any brand and model of CB radio will work, as long as it has the digital display on it. Which means, just about any CB radio manufactured after the mid 1980’s. These are the kinds of CB radios whose frequencies are controlled by a single crystal inside of them. For my mod, I used a Radio Shack TRC-207 walkie talkie CB radio, which is pictured above. I prefer using a walkie talkie CB radio because it doesn’t requiring sticking a huge CB antenna on the roof of my car which might be noticed if a fast food employee starts looking around the parking lot for the culprits.

 
Taking apart your CB radio is just as easy as taking apart the toaster. Remove the screws and pop it open. You may or may not have to lift up the circuit board inside to find the crystal inside. In my particular model, the crystal actually plugged into a socket so I didn’t need to even desolder the old crystal. I just pulled it out with my fingers and then plugged in the new 6.55 MHz crystal. I don’t know how common this is, because in other CB radios that I’ve modified the crystal was soldered to the circuit board, just like in the toaster.

 
Put your CB back together and test it to make sure it’s working. You’re finished! Obviously, you won’t be able to talk on normal CB channels anymore since your CB is transmitting and receiving at a much higher frequency now. But who cares, CB channels are lame anyway. Let’s hop in the car and drive to our nearest fast food establishment to test it out.

Sit near the drive-thru and wait for a customer to pull up. While the customer is talking to the drive-thru speaker, start flipping through your channels until you hear them talking. I’ve found that most drive thrus end up being somewhere in the 16 - 25 channel range. I’ve never found one above channel 30 and only a few on channels 1 through 15. It all depends on how their drive-thru is set up and what frequencies they’re using. Anyway, push down your talk button and start talking to the customer.

The cool thing about using a CB radio to transmit on drive-thru frequencies is that a CB is designed to work for several miles. The headsets that those fast food people wear are only designed to work for about 100 feet. So you can easily overpower the employees, even if you’re several parking lots away. In fact, you may be inadvertently screwing with several other drive-thrus in town without even knowing it. This is more likely when you’re using the kind of CB radio that’s supposed to be installed in a car. Those usually run on 5 watts and can cover an entire city. This is another reason I like to use my walkie talkie. It’s lucky if it will work for even a mile, so I’m only harassing one restaurant at a time.

If you found this tutorial useful, you might also enjoy the video I’ve made on the same subject. It includes much of the same information in this tutorial, but also includes actual footage of us messing with a drive-thru with this CB mod. Enjoy!
