I know when something is kind of half-baked.
I have a really powerful urge to see things work.
You must know in your heart before anyone else does what is going to be good and then follow through.
I started on an Apple II, which I had bought at the very end of 1978 for half of my annual income. I made $4,500 a year, and I spent half of it on the computer.
I write my programs primarily for myself.
The program should know if someone is at the keyboard or joystick or if it is just sitting there idle. It should know if someone is proficient in its use or a novice.
