What you occupy your mind with is of essential importance to your physical and psychological health. Research shows that humans have an average of 60,000 thoughts every day. Although the idea of consistently controlling your thoughts can seem overwhelming, it is one of the most important skills you will ever learn. When you learn to gain control of your mind, you learn self motivation and can begin to take control of your life.
"You are now at a crossroads. This is your opportunity to make the most important decision you will ever make. Forget your past. Who are you now? Who have you decided you really are now? Don't think about who you have been. Who are you now? Who have you decided to become? Make this decision consciously. Make it carefully. Make it powerfully."
-Tony Robbins
When you change your mind, you change:
your body
your daily activities
your environment
