You seem to have recognized that a successful life is possible away from the WTBS, and that's a good first step. I firmly believe that the best way to better yourself is through education, formal or informal, just commit yourself to it.
Now depending on your goals, formal education will have obvious advantages. If you want to something in an established company or do something that requires a license. (Doctor, engineer, teacher, etc.) then a formal education is probably necessary. If, however, you want to start something yourself or help to build something new with someone else, the skills are all that really matter.
But that only covers one aspect of success, if you want to find fulfillment then you should build friendships, practice altruism in your community, pursue your hobbies, travel, experience as much as you can.
