To live your life, you gave up the opportunity to live someone else's. So clearly your life is worth at least as much as anyone else's. Other people seem to act as though their lives have value, though unfortunately none of them can explain why either, except perhaps by themselves observing others treating their lives with value, and circularly repeating this argument.

Your other options are (a) suicide, or (b) becoming a nihilist, which is like suicide but with more thinking.

Are you a middle manager? ;-)

The middle managers are perpetually faced with the prospect that if they choose A, they have to give up B, which is of equal value (within reasonable error bounds). This is a very real part of their lives.

They remind us about opportunity cost, which turns out to be one more thing that they can't hope to calculate. At the end of the day, the average effect of their decision making is net zero.

At zero, yes. But you're also forced to give it up[]. Strange, really.
