Frankly I'm not sure you can succeed if you're just a mercenary (not trying to insult you).
To me it seems you're approaching the problem the wrong way : it shouldn't be about doing like everybody else or trying to be successful just because you think it will make you feel good but it should be about releasing this f* idea that is nagging you since years and that nobody can do better than you.
I have one of those ideas since 2007. One day ... ;-)
