We're all just bags of bones and muscle and hormones; I'll never understand what makes our minds do the things we do. It's like that statue of the monkey holding a skull. We're trying to use a thing we don't understand to understand ourselves. Meshell Ndegeocello
The last three or four reps is what makes the muscle grow. This area of pain divides the champion from someone else who is not a champion. That's what most people lack, having the guts to go on and just say they'll go through the pain no matter what happens. Arnold Schwarzenegger
Fearlessness is like a muscle. I know from my own life that the more I exercise it the more natural it becomes to not let my fears run me. Arianna Huffington
We've forgotten how to remember, and just as importantly, we've forgotten how to pay attention.

Joshua Foer
