So imagine you have a robot. The robot can walk forward and also put his hand out to detect if he's about to run into a wall. You say, "ok robot. Take a step forward. Put your hand out. If you detect a wall, stop. If you don't, take another step. Then put your hand out... and just keep doing that til you detect a wall. Then stop."
You just programmed. Seriously. That's all there is to it. You have to break tasks down into smaller steps and then tell the computer.
Okay, so maybe there's a little more to it than that. For instance you might have to....
- Tell the robot how to take a step. (pick your right foot up. move your right foot forward. Put your right foot down. Pick your left foot up...)
- Tell the electrical parts how to pick the foot up. (Turn this switch on, turn that switch off.)
- Tell the robot to be green and have a pink flower on the top.
- The GUI(Graphical User Interface) designer thinks that the pink flower should really be 13 pixels to the right.
- The robot isn't picking up it's left foot, just it's right foot, please figure out why and fix it.
- The robot isn't stopping when it runs into the wall, please figure out why and fix it.
- Or - some users insist on using Robot Explorer 6, and so you have to write special code to work for that robot version since it refuses to follow w3 standards.
- The robot tripped over a toy and fell over. This was unexpected. Make it say "Error. I cannot continue. Help."

Okay, so it might not be your cup of tea. Maybe you don't like puzzles. Maybe you don't like problem solving. And hey, that's cool. I don't like blood or needles or chemistry or languages or a whole host of other really important things necessary for other careers. But when it comes right down to it, I *love* programming. And you don't have to be scared of it anymore.
