I believe that the only way to be as fast as I wish I am, is to think myself exactly as strong as I actually am. I constantly overreach, and even more often arrogate capabilities to myself that I don’t actually have.
Want to know how I get injured?
I blind myself to the interface between my body and the world, and I use willful ignorance to dedicatedly circumvent certain truths about the world—truths that accelerate at 9.8m/s² (32.1ft/s²), and, in my case, slam into my feet with around 450 lbs of force. Somehow, I have to bully myself into greater awareness, and greater humility about myself and the world. Somehow, I have to find a way to train healthy and safe.
And to that end, I use the term false performance. I invite you to use it as well.
