I console myself that this is why I never got fabulously wealthy. That brilliance is no guarantee of wealth. You need luck, too.
But the truth is, you also need to do the work. I used my conclusion about luck as an excuse to not even try. Not even in some grand way. Just in the grinding everyday way. In the way of, "You know what I should do?! I should ... meh. That'll never work."
Take it from me, kids. If you want to do something great, do it while you are still young enough to believe it's possible.
