Just because you love something doesn't mean you have to be the best at it. For that matter you don't even have to be good at it. All that matters is you enjoy the time you spend doing it.
MANY years ago I was a "fast" runner. I enjoyed it, but found myself running for others rather than myself. Today I run for myself. If I see a duck and want to watch it I'll stop and watch. I may not be as fast as I once was, but I enjoy the time I spend doing it, and that is all that matters to me.
I still push myself at times, as I find joy is seeing what the limit of my body is, but I do it on my own terms.
