You achieve your potential by merging your soul with your physical body. That means the spiritual part of you (everyone has a spiritual part to them) has to be aligned with the physical part of you. The way you do this is through your mind. Your mind is the link between the two.
I don't mean your brain, I mean your mind. The part of you that works out right from wrong and allows you to do more than function like a robot or an animal. You probably don't know that with your mind you have created everything you see. Everything has originated from your thoughts.
Some of your thoughts create your emotions and your emotions are the force that pushes you to act. Your emotions cause you to act in ways that you don't want. Some very powerful emotions are fear, anger, jealousy and envy. There are many more subtle emotions and variations of common emotions that everyday, dictate to you how you should act.
