You don't seem so convinced. Change your language, say "I'll become a developer". Also, I don't think you need to go back to school or get a certification of any kind. I believe there are plenty of cheap/low cost options out there. You need to develop skills... skills that create value for others and obviously for you too. But hey, what do I know, I'm not successful enough yet to give this kind of advice. Gotta keep hustling.
