Success is the sum of small repeated efforts, day in and day out.

We learn more from failure than we do from success.

Nobody said it’d be easy, they just promised it would be worth it.

Lose an hour in the morning and you will spend all day looking for it.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Run in the morning before your body figures out what you're doing
