A friend of mine who has done well for himself in retail and later real estate said at one point that if he were to start over he'd consider plumbing: Getting a good plumber in his area was hard so those who were could both be picky and expensive. Of my other close friends friends those who did best so far did by doing well in sales (graduating to running their own), blue collar mechanic (team lead -> manager -> get some spre time, starts investing and building his own) and a number of people going the carpentry to real estate route. One of those who has done well has gone via college/university.
