Breath

Your breath is one of the most powerful things in your body, maybe besides your brain. If you can harness your breath, anything becomes achievable. This comes along with climbing or anything anyone can be doing. If you can breath and control your breath then your mind becomes less worried about the future or the past and you become involved in the present. Whenever you feel stressed, overwhelmed, or worried about the past or the future, control your breath, stop thinking, focus on the present, and everything goes away.
