I guess after all those stories, the question really boils down to motivation: how much do you care about money, and do you want to sacrifice other things to achieve stupendous amounts of it or are you happy with just 'enough'? Many people seem to find that ultimately life is too short to just stack up cash ignoring everything else for more than a short few years (if even that)... one needs companionship, interests, family, quality of life.

Health, both mental and physical, is definitely one thing to put ahead of cash, perversely particularly when you are young because you are essentially gambling with your entire future, and there's more of it to throw away. That said, you don't have family yet so suicide as described in the article probably seems a more acceptable out... one might assume that suicide rates lower with children.
