Start a strtup in case you want to make business, to have fun.
Investors are not your bosses. Their goal is the same: make your company perform better.
Don't be afraid of them :)
Bosses aren't someone to fear. I think investors are overseers of my performance and people to whom I am accountable, therefor, my bosses. I'm not afraid of them. Never work for people you are afraid of.
