What Are the Most Important Problems of Our Time?

There's this very opaque question that i have not been able to shake. I say it's opaque because nobody has a good answer to it. The answer basically is, what should i do with my life? And so the wrestling with that opaque question has been something i've been thinking about a lot. If you accept the fact that your time is limited, and you want to make some small contribution in your little corner of the universe, it makes sense to ask that question.
