I am currently reading "My Grandfather's Son." There is much to comment about this book; something that stood out to me as I was reading today was this prayer that Clarence Thomas said he recited daily through some difficult times.

A prayer attributed to St. Francis of Assisi:

Keep a clear eye toward life's end. Do not forget your purpose and destiny as God's creature. What you are in His sight is what you are and nothing more. Do not let worldly cares and anxieties or the pressures of office blot out the divine life within you or the voice of God's spirit guiding you in your great task of leading humanity to wholeness. If you open yourself to God and his plan printed deeply in your heart, God will open Himself to you.
