How can I grow mentally?
Coaching is to your mind what working out is to your body.
After an intense work out session, you can feel it in your body, you have to rest. Your mental strength requires the same level of training. As an example, a key mental muscle you may want to start working on is Self-Integrity. It consists of doing what you tell yourself you will do. The goal is to create self-confidence. When you start trusting yourself, you ultimately progress a lot faster in life.
