As human beings we are gifted with the power of self control; mind over matter. An incredibly efficient tool when fueled with the proper dose of will.
When our heads are at odds with our hearts, bodies, or souls, we have a choice to change the situation; to push through the day when our bodies are exhausted, or prioritize our needs over the wants of our hearts.
We will eternally have a choice, and there is no doubt, where there is a will there is a way.
I believe the will of the human race is in too many cases selfish. There is a will to get ahead but not as a team, a will to succeed but not to work, a will to teach but not to learn, and a will to prove correctness but not admit to incorrectness.
Our human race lacks the will to love, listen, apologize, and forgive, in other words, our human race lacks strength.
