No, not at all.
I wouldnt consider myself financially successful in the way you are probably thinking, but I get along just fine...and I know that if I keep going at this rate I will reach a level of financial "success" that I think many people would be comfortable with. Nothing major, but respectable. Nor I or the people I work with (who make much more than I do) are cutthroat in any way. Im getting to be successful by treating my clients well and by making sure the people that work for me are successful. If they make money, I make money.But yeah, it depends on your line of work.
