The honest truth...There is really no market for someone that is kinda smart, but lacks the follow-through / ability to execute. Personally, I rather have more of the latter and less of the former, honestly.

So, what do you do? Start small. If you want to be an entrepreneur, great! Build small projects. Even the best of us will get overwhelmed if we willy nilly start something unplanned, once the scope starts getting unwieldy. It might be worthwhile to start getting involved in open source, where the scopes of each ticket are very narrowly defined and you can start with easy little things (documentation, simple fixes, trivial functionality). Then, work your way up.

Good luck!
