well the first thing you have to do is listen to negative people. They will bury you in a hole if you let them. You can do it and it sounds like your diversified. Just work at it be honest with everyone and grow slow so you dont get over your head. Insurance is a big deal so you gotta keep that in mind as well. If you have no more free time hire a helper till you get enough clients then quit your teaching job and let your helper go if need be. Biggest thing is to believe in yourself and not listen to the losers that have made nothing out of there life and wanna bring you down with them.
my 2 cents...
