"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."

I was wondering if this was actually true? For a little perspective, I am 41 and have been self-employed since I was 20 (I am not a programmer), and I have ideas constantly. There are several books filled around my house with notes on business ideas, and now I have a secret Posterous account I email whenever the next idea strikes. My wife finds great humor in this - sometimes I will have the same brilliant idea more than once - 'You thought of that one two years ago dear' will be her response. So to me, ideas come constantly like a raging river. I read posts by others, and they seem to have problems coming up with ANY ideas at all. So the question is this:

Do you think being self-employed helps with idea creation or not?
