From greeneyedkzin:

It's like Modern Portfolio Theory. Diversify. That way, if the opera isn't good, maybe the play will be, or the ballet, or the art show, or the clothes, or the rugs. And if you buy a little of all of them, you can't overspend on ANY of them. Keeps it in balance and manages risk.
