I remember reading a story, I think in the early nineties though it's probably a lot older than that, about a man who would have streaks of good luck, alternated with equal streaks of bad luck. So after a short streak of good luck, a short streak of bad luck would follow. The story dealt for a large part about a huge streak of good luck in which, among other things, he won the lottery. Knowing that an extreme streak of bad luck is coming up,
he tries to commit suicide--and fails, which is the first event in his new streak of bad luck.
I think it was a short story, not a novel(la). It may or may not have been written by Harry Harrison.
Does anyone know what it's called, and where I can find it?
