Walking into a gym where you don't know anybody can be just like walking into a bar or job where you don't know anybody.

Just because you're a CEO doesn't mean you're dying to go to work.

Your psyche can really help you and it can really hurt you.

Emotional conditioning is crucial because once you get to any level in sport -- whether high school, division I collegiate, the nationals, the Olympics, or even as a weekend warrior -- everyone is pretty equal physically. It's those who can handle noise, stress, pressure, and distraction who are the ones that win.

Every athlete has a piece of toughness. You need to be mentally tough to train hard because it hurts. And oftentimes, as a growing athlete, you make more mistakes than you don't. Frustration and injuries happen, and you've got to be tough to keep going.

If you take a couple of minutes to mentally prepare yourself -- that can help. The killer piece for a weekend warrior is expectation. It's really hard to go back after 20 years and play a sport again … and people don't prepare for that and get disappointed.
