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.
This is why grad school was so much better than work is now. Then, I get to pick projects, manage and engineer them myself, and do my own marketing. Now, I do one little piece of nothing on a project which will probably get re-engineered by my manager next week.
And, of course, there was more drinking then. :-)
