Based on the discussion that went on for one of our previous postings on how to quit your job right, I’m interested in how big of a motivational factor a poor work environment is to entrepreneurs.

Personally, my I didn’t start working for myself as a result of personality friction, but rather as a need for further personal growth.

So, an open question:

What is the strongest factor driving you to start your own business

Alternatively, what keeps you from doing so?
