Physically I was strong, but I was not even close to mastering my mind. - David Goggins

Insanity is doing the same thing over and over again and expecting a different result.

You must recognize what you are about to do, highlight what you do not like about it, and spend time visualizing each and every obstacle you can.

No matter what you or I achieve, in sports, business, or life, we can’t be satisfied. Life is too dynamic a game. We’re either getting better or we’re getting worse. Yes, we need to celebrate our victories. There’s power in victory that’s transformative, but after our celebration we should dial it down, dream up new training regimens, new goals, and start at zero the very next day.
