Nice to see someone who is interested in permaculture!
TITS McGee, I think the best thing you can do to solve the world's problems is get to know yourself. Figure out who you really are and become that person. Being a JW retards the process of understanding yourself, because you weren't allowed to have a self. We were all trying to fit into a mold... Once you know your best and worst qualities, you can figure out what kinds of circumstances fit you the best, and where you can make the good qualities count and turn the bad ones into something useful.
Also, don't worry too much. Keep an open mind. Keep your options open. If you're the right guy, with all the right qualities to think about a certain issue, you'll be drawn to it naturally, whether it's a field of study, or even a person.
