Should I quit my job and go self employed?

[Dave G]

I have a corporate job where I work 40 hours a week. The pay is decent for entry level, but I cannot see myself working in the corporate world for much longer. It is so boring for me. I have been working on developing my own business on the side. I am a tutor, working to become a personal trainer, and make a little money online. I don't make enough on the side to survive off right now though. I make about 1/2 what I would need to survive, plus tutoring is obviously fairly seasonal. However I have not started personal training yet and I am hopeful my online income grows as well. I have about 6 months of savings. I am planning to attempt to cut my corporate job back to part time in 2 months, but I'm not sure they will allow me to. If they don't, should I quit? What should I do? I feel like right now I don't have the time or energy to really market and grow my side businesses.
