People say that the ultimate question is the meaning of life, but I think that;s a cop-out. People care very little for notions as abstract as that, although it can be fun to debate at the University duck pond, in terms as sweeping as they are impersonal.
A far better question is “Do I matter?” and I think that most of human activity can be divided into two types: that which makes a person matter, and that which makes a person appear to matter. It’s a yes/no question and everybody wants the answer to be yes. Failing that, they want other people not to know that the answer is no.
