“When you start looking at a problem and it seems really simple with all these simple solutions, you don’t really understand the complexity of the problem Then you get into the problem, and you see it’s really complicated. And you come up with all these convoluted solutions  That’s . . . where most people stop But the really great person will keep going and find the key The underlying principle of the problem. And come up with a beautiful elegant solution that works.”—Steve Jobs (quoted by Steven Levy, The Perfect Thing).”
