You cannot hide your thoughts, they are reflected in your attitude, expressed in your actions and repeated as habits established as your character, and ultimately become the outward manifestations of one's destiny.
The only thing that makes a difference in your life is the way you think at this moment. You are not bound by the mistakes of the past, or the limitations that you perceive, in the future. Your potential is unlimited because you are free to choose your thoughts at this moment, and what you think at this moment determines the entire future direction of your life.
