The fastest way to become the Master of your thoughts and emotions is through challenging situations.
If your life is going along fairly smoothly, there are not the same opportunities that enable you to strengthen your power and become the Master of your thoughts and emotions.
You see, even challenges are beautiful opportunities in disguise.
I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
