It's always too early to quit.
What you do today can improve all your tomorrows.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
If you can dream it, you can do it.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
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.
