If you have a big splash of ecstasy in your life every day you are going to teach students something finer than "buy low<br>sell high". Maybe you'll teach them, not by what you say but by who you are, to live their lives as a standing affront to the ravaging mercantile mentality.
You're going to fall down, but the world doesn't care how many times you fall down, as long as it's one fewer than the numbers of times you get back up.
