Fear pounds on the door to our heart demanding to be let in. Joy is modest and often comes into our lives like a shy person entering a room; it can take a while to even notice it's there.
If it was as logical as that, I wouldn't continue to feel as bad as I do. I know what you're saying, and you're absolutely right in a way. But logic and rationality only go so far. Then you know what happens? Ha! Then your heart adds its two cents and everything reasonable goes right-out-the-window.
The only question that nobody ever asks is: What breaks your heart? I think that should be asked of all "artists."... So, what breaks your heart?
It took me less than half a lifetime to realize that regret is one of the few guaranteed certainties. Sooner or later everything is touched by it, despite our naive and senseless hope that just this time we will be spared its cold hand on our heart.
