I'm a big believer in doing things that make you uncomfortable. So, we live in a world where we want to be as comfortable as we can. And we wonder why we have no growth. We wonder why - when the smallest thing in our life gets difficult - we wonder why we cower and we run away.

My whole thing now is I know how to think properly to be successful in all aspects of my life. It's not about ultra running or being a SEAL or pull-up records: it's about if you want to be better you, have to change your perceived limitations and take the barriers down.

Before you start a goal - let's take care of our insecurities because they are going to surface when you put yourself in the crucible and you're suffering.

When you tell a recruiter that you're almost 300 pounds and you want to be a SEAL, it doesn't go too well. I got hung up on a lot.

Read a record number of books in a given month. If you're focused on intellectual growth, train yourself to study harder and longer than ever before.

I swam underwater for 50 meters at a time and walked the length of the pool underwater, with a brick in each hand, all on a single breath.

Back in the day, what motivated me was overcoming myself. Now I believe in being a leader. I've done it all - I'm good. Now, it's about setting an example for others to follow. I can't just talk it - I have to live it.

When you're in hell, you forget how great you really are because you're suffering and you forget the great things you've done.

The reason I became 297 pounds is because that was comfortable. What was very uncomfortable was running. What was very uncomfortable was being on a diet. What was very uncomfortable was trying to face things that I didn't want to face. And I also realized, when I was really big, I had no growth. Why? Because I was living comfortable.

I had a rough childhood coming up, and I just took all that negative energy and made it very positive for myself to drive me. I'm a very driven person. I have passion that almost scares people, just to be successful and make it no matter what.
