It's like a muscle - if you stop going to the gym or stop running, you get weak. The military teaches you these great values, but we don't keep up the discipline on our own, and we lose it. So wherever you go, keep that discipline up.

You have to be willing to go to war with yourself and create a whole new identity.

Remembering what you've been through and how that has strengthened your mindset can lift you out of a negative brain loop and help you bypass those weak, one-second impulses to give in. Even if you're feeling low and beat down by life right now, I guarantee you can think of a time or two when you overcame odds and tasted success.

Our whole life is set up in the path of least resistance. We don't want to suffer. We don't want to feel discomfort. So the whole time, we're living our lives in a very comfortable area. There's no growth in that.

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.

Our whole life is set up in the path of least resistance. We don't want to suffer. We don't want to feel discomfort. So the whole time, we're living our lives in a very comfortable area. There's no growth in that.
