Agreed. And I think it should be less about "the rest of your life" and more about the next best opportunity. Do the best you can in the place you are now, and it will lead to possibilities that you didn't know existed or were possible. I am not rich or famous and I wouldn't say that I've made any significant impact on humanity, but I am very happy in both my work and personal life. Ten years ago, I would have never imagined my situation would look like it does now.
