Life is often compared to a marathon, but I think it is more like being a sprinter; long stretches of hard work punctuated by brief moments in which we are given the opportunity to perform at our best.

We all have limitations. I don't have the right genes to be an Olympic weightlifter. I don't have the right genetics to be an Olympic sprinter. Or gymnast. Sure, if I trained my whole life, perhaps I could have become fairly decent in those sports.

Propaganda is a sprinter, but truth is a long-distance runner.

My goal is to get another 30 years out of this business. So I need to figure out the fuel to do that. And so far I think it's respect and quality and company not celebrity or box office or stardom. It's not a sprinter's approach. It's more like a long-distance thing. You can stick around a lot longer if you kind of slow-play it.

The poster boy for our superabled future is Oscar Pistorius an increasingly famous South African sprinter who happens to have had both of his legs amputated below the knee. Using upside down question mark-shaped carbon fiber sprinting prosthetics called Cheetah blades Mr. Pistorius can challenge the fastest sprinters in the world.
