I'm usually good at things. I learn quickly. I won't give myself any credit for this because I've always been this way. I know you didn't ask for advice, and I'm sure you've tried everything but if you lack natural talent there is something you can do to emulate it.
Imitation.
Whatever it is you want to be good at, you want to find someone else who is already good at it and just copy what they do. Even if you fail and stumble on the way and you are never able to perfectly imitate what they are doing, you will likely still end up performing better than the average even if only by a little, and if the starting point is "good at nothing", I think better than average is a good place to be.
