Alex Honnold on Human Performance (part 1) – Where's the Limit?

Just to spend a lot of hours doing something and not have success or meaning—you might as well not spend the hours doing it. There are a lot of people who say, 'I worked 15 hours today, and I work Saturday and Sunday,' but nothing happened! That, to me, is not effective.

When you start to know what's possible, then people are able to push a little harder. It's like when Roger Bannister broke the four-minute mile. As soon as he did, everybody else started breaking the barrier because they knew it was possible.

The goal [of training] isn't to be sore; the goal is to see results and improve.
