Sure, it might be more difficult for me to learn to play the piano than for some virtuoso, but my life will still be richer after I learn it, instead of giving up because it is difficult. No?
This isnt to say I don't believe we should do things we're bad at -- I think broadening our aptitudes is good for us -- but you do have to consider the opportunity cost of piano versus another option.
The very process of working to improve at something you're not good at (or have any natural aptitude for) is a wonderful way to learn how to adapt, compensate for weaknesses, and overcome adversity. I know I'll never be a weightlifting champion, but aside from the health benefits, I lift because it's something I'm not good at.
I've been told in the past I'm good at solving complex problems I've never encountered before. I just show them my notes on how I solved it and say I'm not good at all, just persistent and willing to learn as I go. I notice a lot of people give up at the first sign of adversity. I might too depending on the criticality but that doesn't mean I accept defeat.
