Think sad thoughts and you will become sad. Think happy thoughts and you will be happy. Smile and you will feel elated. Place your hands on your hips and you will feel powerful. Repeat to yourself that you are handsome and you will soon believe it. Tell yourself that you can do anything, and your body will mobilize to make it happen.
The mind-body connection is powerful. We can fool ourselves into becoming our ideal selves by allowing our bodies or minds to take the lead. If we can harness this connection, we can achieve our ultimate desires.
Whether you begin with the mental or somatic pathway is besides the point.
The point is, change begins within.
