Man! I wish my boss had read it 5 years ago. I could never understand why I was not motivated in my job at all even though my boss was really brilliant. It basically reduced to this. No matter what I did the boss always had 2 cents that had little impact on anything but made be less interesting in doing the work. But for my next job the boss was much better, instead of saying change this and change that he would often ask me why I made certain choices and what inspired me. He would then say "ship it" but the questions he raised made me wonder how I could make things better.

But the advice is something everyone must learn.
