I used to be on a team with a guy who was much more talented than I was. He could always outclimb me and when sprinting he'd pass me and look like he was barely working. But he was lazy. Always complaining about how sore his legs were and though he had the ability to drop almost everyone on a climb, he was never the first over the top.
It took me a while to realize that he just didn't like pain. Simple as that. I on the other hand was stubborn enough in my desire not to be dropped or to be last that I'd suffer like a dog at every sprint and on every climb. At the risk of sounding egotistical, if someone with his physical talent had my drive, he'd be tough to beat.
