I used to race bicycles competitively, and our coach grilled into our heads: "It's you vs. the track. The other racers are just obstacles in your way. You are not racing them, you are racing yourself." I was a mid pack racer, but that mentality, of focusing on personal growth was huge.
You define success for yourself. And by your measure, others may be more successful on your own measure, but they are not you.
I'll also add the trite: "hard work will be talent if talent doesn't work hard." My brother was a natural racer, but he hated to practice and got beat by riders who were better conditioned all the time.
He never had to beat them, he just had to beat himself.
