If you have 'solved' the money problem for your personal life and seems looking for 'purpose' and 'positive feeling reward' have you considered giving time to charity/community (specificaly 'local' ones near you live) ?

I think a common lacking in those (smale scale) organisations is sometime basic event/communication/money management, with often more enthousiasm than skills.

I don't know on the USA (I assume your from here) but hackerspaces and derivatives can allow you to keep in touch with the startup world while helping a lot of enthousiast people and being emotionaly rewarded.

Of course that mean taking a standard job to live. In Europe (dont know for USA) it can even help you land a real part time job after some time.
