Grit is overrated. Determination is what matters. Grit implies you'd grind yourself down at a task you know probably won't go well for you, just because you'd never give up, even when you get zero enjoyment or satisfaction out of it.
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.
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.
