The Thing Nobody Says About Lifting Weights

> The thing that nobody talks about is that lifting provides evidence of change and improvement in the form of muscle development. Once you realize you can change your body, you start seeking out other areas of your life.

Related, you can't really "cheat" per se. Either you can lift more, or you can't. You can either run further or faster or you can't. I'm a solid proponent of self-esteem being driven by personal views of yourself and things you have accomplished (distinct from someone telling you you are good, you know you are good because you did something). When you hit the new personal best on an amount lifted, there is real achievement.
