I hope that you see amazing results, and you continue to enjoy yourself!
I recently quit my job without having another job lined up.  My friends and family encouraged me to quit because of the environment I was in.  I'm going to attempt to do work-at-home gigs while I figure stuff out.  It's scary, but I'm trying to remain optimistic that this was the right thing and everything will work out.
