Good on ya! I too often people saying - oh, I'm not in my 20s any more so I can't give up my job making $$$ and supporting my family. News flash!!! It's all about priorities and what's important to you. If your dream is to do a startup but you feel hemmed in by your house, car, etc, start thinking about what is important.

On the other hand, I'm working for a small non-startup software company as a salaried developer and love it. I get to focus on developing software and not running a company :)
