Being genius helps with that.
Same with the recent Steve Jobs threads. Or any thread featuring prominent programmers or founders.
I think immediately reaching for the "genius defense" (whether deserved or not) does far more harm than good.
Exceptional labels are often used to abdicate responsibility of the mediocre for their own mediocrity.
It's easier to label someone as special than it is to admit you didn't put in the time they did, or that your fear of failure prevents you from trying.
This particular Woz story doesn't scream of "genius" to me.
It screams of curiosity and confidence, a fearlessness, of a young and foolhardy geek swimming in opportunity and it enabled him to discover some interesting, innovative things.
The part where his (probably senior) hardware dept. colleague trolled him into completely ripping apart his work and redoing it all for cosmetic reasons with a single sentence saying "Steve, you mean you’re going to go with less than perfect?" had me laughing heartily, and caused me to reflect on the times similar things had been done to me early in my career.
Woz did his thing under much the same constraints as Tramiel held the Commodore engineers to, keep the chip count, and thus the price, down.
Every time Woz added a chip, he carefully looked for very way he could use that chip for different tasks.
