when is it time to stop calculating risk and rewards, and just do what you know is right?
I think a better question would be, why wouldn't you be doing what's right to begin with? this question doesn't make sense to me, because people who have to weigh risks and rewards generally make good decisions, or at least decisions beneficial to themselves. it's a whole different story on whether or not it can be deemed "good" or "bad." you'd have to know the story behind it. if you're not already weighing an outcome, you're not really making a worthwhile decision. all it shows is you don't care. that's when you stop. either that or you really have nothing left to lose. and I guess at that point, you shouldn't care about what might happen. just do it.
