Deep within the soul lies your our true strength. Strength that can only be reached by being broken. Only when the spirit is tested and the will is bent to a degree that would cause any normal human to give up.
When you give in, and you will, that doesn’t mean you are weak, it means you are human. Through consistent practice, one conditions the mind and body to quit less and go farther before giving in by means of this inner strength we possess.
Behind each loss and time you gave up is the path to the most hardened version of yourself. The version of you who refuses to lose and is tired of the physical and mental relief that comes with quitting. So as you sit there wondering if you have what it takes, remind yourself that most people stopped trying LONG before you. So pick yourself up and get back to it.
