It seems like a good example of the described problem, however. I could also attempt to make a table, and I will conclude that I have seen many better tables made, which could make me feel bad.

The hard part is letting go of being the best, or even succeeding, in my opinion. It's cliche, but the attempt is what matters. If you run a marathon to win it, you will almost certainly be disappointed; but if you run it to be a better runner, to be healthier, or simply to say you did, you will be happier having done it than having not done it because you know you won't win.
