Like most ENTP's I have no difficulty making money, and never had, I've been working since I was about 11 (partime in family businesses until I was 17 or so).
My income goes up and down depending on if I'm between jobs or not. When I get fed up, I tend to resign without something to go too.... a bad habit I need to get over.
I make good money these days, but then I do feel like I have worked for it, and deprived myself of other things in order to excel. I tend to feel a little unbalanced toward work at times... get too invovled/sulked in.
I need to work at balancing my profesional life with my recreational life.
