You don’t get better on the days when you feel like going. You get better on the days when you don’t want to go, but you go anyway. If you can overcome the negative energy coming from your tired body or unmotivated mind, you will grow and become better. It won’t be the best workout you have, you won’t accomplish as much as what you usually do when you actually feel good, but that doesn’t matter. Growth is a long term game, and the crappy days are more important.

The real test is this one: When you're alone in a room, when you're in a private place and nobody else can see you, what do you choose to do? Eat well, or eat poorly? Exercise, or watch television? Practice something, or do nothing? The best version of the truth appears to you and you alone, when nobody else can see. This is the test of discipline, and it's what makes the difference in your life. It's what regulates your own system and guides it. The individual alone comprehends it.

I am a public person and I have my private life. It's important for me that my private life stay private, that what I share with the people is my public personality.

When I go on vacation I just like to do nothing - just hang out at the beach, go eat the best restaurants, and do nothing.

Because Conor McGregor is so confident - he goes there 'I'll beat this, I will do that' - If I would be his coach I will tell him all the time, behind closed doors, how dangerous [Nate] Diaz is and how much of a war this fight will be and how painful, and long, and uncomfortable it would be, and to get prepared for the worst day of his life.

My mentality is like a Samurai: They used to every day work on their technique to make themselves almost perfect. Because perfection is impossible, but every day, you get closer to perfection.

There is a difference between a fighter and a martial artist. A fighter is training for a purpose: He has a fight. I’m a martial artist. I don’t train for a fight. I train for myself. I’m training all the time. My goal is perfection. But I will never reach perfection.
