“It's so easy to be great nowadays because everyone else is weak.”

“We live in a world where mediocrity is often rewarded. You have to be willing to be uncommon amongst the uncommon.”

“You have to build calluses on your brain just like you build calluses on your hands.”

“Motivation is crap. Motivation comes and goes. When you're driven, whatever is in front of you will get destroyed.”

“In the middle of a long run, the only person you can talk to is yourself. And the conversation better be good.”

“Don't stop when you're tired. Stop when you're done.”

“When you think that you are done, you're only at 40 percent of your body's capability.”

“Suffering is the true test of life.”

“You are in danger of living a life so comfortable and soft that you will die without ever realizing your potential.”

“Who are you when it's three in the morning and no one is watching?”

“Pain is the body's way of ridding itself of weakness.”

“There is no finish line. There is no retirement. It's a never-ending process.”

“The race is long and in the end, it's only with yourself.”
