You'd be hard pressed to find a rewarding skill where you don't absolutely suck for at least a year when you start practicing it. If you pick up something and you don't fail immediately and often, it's probably trivial.

Grit is finding the smallest gains and consistently hitting them in a difficult situation. It burns time to hold space. It works best when you need to hold something at nearly any cost. Its rare morale holds that long without a strong structure backing it up.

I agree it is overrated. Was just defining grit. I think it matters to have a combination of traits, whether it be grit + determination + ....

For fun, my coded solution for determination:

  while(!found()) continue;
