While cleaning out a drawer, I came across a small three ring binder that I used during seminary as a journal. Paperclipped to its pages was a photocopy of a hymn by H.C.G. Moule that was always helpful to meditate on and pray:
Lord and Savior, true and kind,
Be the master of my mind;
Bless, and guide, and strengthen still
All the powers of thought and will.
While I ply the scholar’s task,
Jesus Christ, be near, I ask;
Help the memory, clear the brain,
Knowledge still to seek and gain.
Here I train for life’s swift race;
Let me do it in Thy grace:
Here I arm me for life’s fight,
Let me do it in Thy might.
Thou has made me mind and soul;
I for Thee would use the whole:
Thou has died that I might live;
All my powers to Thee I give.
Striving, thinking, learning still,
Let me follow thus Thy will,
Till my whole glad nature be
Trained for duty and for Thee.
Dan Greenfield 
This is my high school anthem.
I went to a secondary school in Nigeria. It was a Methodist missionary school, Birch Freeman High School. We had to sing this song like a National anthem, I loved it and I still sing it, thirty six years after graduation!.
