Learn to Relax
If your brain had a volume dial, what notch would it be at right now? The noise level in your head greatly affects your ability to work and relax effectively.
Practitioners of Eastern disciplines such as martial arts and yoga know that clarity, strength, and power can only come from a place of quiet calm. In quieting your mind, you essentially turn down the dial in your head so that you are more present and less distracted by the din of thoughts, worries and fears.
