I don't think that you can draw a limit, I think the limit has to be inherent in some way. You're pursuing wealth - to what end? Your end will always (eventually) be pleasure (if not, then that's a bad sign), but do you have good reason to believe that the specific pursuit of wealth will end in net pleasure? Has it worked in the past? When will it pay off? What will happen next?
I like where you're going in this paragraph! What are the ends you're working toward? That has to be answered by someone "pursuing wealth." Wealth for wealth's sake is empty. Wealth for a specific pleasure or pleasurable goal could be something different. Although it could also be problematic if it's working for wealth only to be enjoyed decades from now and not finding any pleasure now. If I've misconstrued your intentions with those lines, just let me know.
I would disagree, at least for my own self, with the wisdom in pursuit of an ambiguous goal that may never pay off when there are so many strong pleasures (mostly) easily available to me. That doesn't mean I don't believe in hard work or that I never choose pain for a greater pleasure
Same here. I think you're raising some really good points here.
