You need to be a programmer to understand these:

0001. No matter how many times you call an "X" no one gets jealous.
0010. Using the same line over and over again always works!
0011. Accurate comments make everyone happy.
0100. If something is not working correctly you can always change the source code.
0101. Programs don't get offended if you let your friends play with them.
0110. When you write a useful function you can add it to all of your programs.
0111. You can write a program to take input from multiple sources without complaining.
1000. You can not run a program for years and it is always ready when you want it.
1001. You can play with more than one program at the same time.
1010. Programs don't complain when you use "helper" programs.
1011. Programs exist to serve YOU.
1100. No one goes to jail when they kill a program.

Yes, I'm numbering these in binary.

That is my short list, I hope you like them and feel free to add your own in the comments.
