Farrah Gray, young male multimillionaire and author of "Reallionaire" suggests asking oneself this question pertaining to such a path, "What would I do for years and years to come and not have to get paid?"
There are some jobs that require a certain amount of college or training. You can do it though with hard work, motivation, and dedication to learning and studying.
