I feel like implicit in this framing is the idea that one's sense of value is linked to where one measures up in some arbitrary task. Should I feel worse about myself if I'm only in the 95th percentile for some activity I enjoy rather than the 99th? Most things worth doing are more enjoyable the more skilled you are at them, but of course our lives are finite and we have to make choices that might limit our development of any skill. But the more I am worried about where I measure up, the less I am enjoying the thing for what it is. As the saying goes, comparison is the thief of joy.
