I often use that as a source of encouragement rather than defeat. My two favorite sports are snowboarding and muay thai which are filled with people who’ve been practicing before they formed memories. If a child is better than me then I’m almost certainly capable of becoming that good with continued practice. Even if it takes years it’s something to aspire to regardless of the relative age difference. I was one of those kids who was way better than a lot of people on a dirt bike. I was put on a dirt bike at the age of 4 and don’t even remember learning, so it’s not like it’s a fair comparison. Just run your own race and aspire to be like those around you.
