If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
The best physicians are Dr. Diet, Dr. Quiet, and Dr. Merryman.
The most wonderful study of mankind is man. Relieving human suffering and diffusing universal knowledge is humanitarian.
