I would first do it part time to hammer out the ideas and to build a prototype. Once you have the vision, run with it and go full time. It's really hard to be successful when you're doing it half-a$$. Really?! What do you have to lose? If you think you are burden with responsibilities now, the future will hold even more responsibilities and constraints. It's better to take risks when you're young and unadulterated. If not now, when?
