All of the startup founders that I know are internally driven and do not depend on the environment and/or circumstances to motivate them.

Just because I have more time than you does not mean that you use your time more efficiently than i do. I have 12 hours a day to code and thats just what I do. I dont sit around for 9 and code for 3 just because I have time to. I code for 12 because I want to. I can also fly across the country on a moments notice and stay up all night for a client if needed.

Can startup dad?

My point is that IMHO nothing that limits your flexibility and distracts you can possibly give you an advantage as a startup founder.
