I think I may have misstated my feelings on this earlier: “Luck” is nothing more than how you interpret your life.
So if you lose your paycheck at the Friday night poker game, leave early… and run into the future Mrs. Right, then perhaps your luck was better than you could have imagined. And if you stopped looking for possibilities in your life after that last hand of poker, you might have thought, “I’m just unlucky.” (On the other hand, the winner of the poker game maybe could have been in the same position you were when you met the girl, and other things being equal, she may have been right for him, too.)
If your wife leaves you… and then you find someone better, then weren’t you lucky that the old battle-axe is out of the picture? (I can tell you for certain that I’m luckier than anyone she hooks up with in the future.)
If you don’t get the job promotion, but don’t get the stress and headaches and long nights that come with it, maybe you sidestepped a heart attack… and never even knew it. (That lucky guy who got your promotion went down in a job-related plane crash a couple of years later.)
Luck is how you interpret your life, I think. In that sense, I’m a very lucky guy. All the time, including when I lose, when I get sick, whatever. I just don’t always know how my luck is going to pan out. So far, so good.
On the other hand, since we all die eventually, anyway, maybe we’re all unlucky. So what do I know?
