"We can't win against obsession. They care, we don't. They win."
- Ford Prefect, The Hitchhiker's Guide To The Galaxy.
If I wanted to be the greatest baseball player in the world, I could work all of my life with that goal in mind and still never get there. Because someone out there was working harder than I work, at a younger age. That person is taking unsafe dosages of steroids, just to get that little bit more muscle that might make the difference. That person is sacrificing a social life to practice pitching. That person has given up everything for this one goal.
We have a tendency to measure everything in terms of "bests." The best baseball player, the best journalist, the best musician. But our biggest asset as humans is that we don't have to be good at just one thing.
There are kids who can play YYZ on guitar before they turn eight. There are kids who are writing software for their home-built computer, and I don't even know what C+ means.
If we measured everything in terms of bests, the only people who would count for anything would be the people who threw themselves at something early, with animalistic determination.
We can change the world without being the "best" at anything.
You can't be the best, so be unique.
