You Weren't Meant to Have a Boss
From the always excellent Paul Graham. And I think this applies to lots of different types of people, not just programmers.
”An obstacle downstream propagates upstream. If you’re not allowed to implement new ideas, you stop having them. And vice versa: when you can do whatever you want, you have more ideas about what to do. So working for yourself makes your brain more powerful in the same way a low-restriction exhaust system makes an engine more powerful.”
