Never tire yourself more than necessary, even if you have to found a culture on the fatigue of your bones.
Our fatigue is often caused not by work, but by worry, frustration and resentment.
Fatigue dulls the pain, but awakes enticing thoughts of death. So! that is the way in which you are tempted to overcome your loneliness -- by making the ultimate escape from life. -- No! It may be that death is to be your ultimate gift to life: it must not be an act of treachery against it.
Men weary as much of not doing the things they want to do as of doing the things they do not want to do.
Our greatest weariness comes from work not done.
Nothing is so fatiguing as the eternal hanging on of an uncompleted task.
Fatigue makes cowards of us all.
You've got to be in top physical condition. Fatigue makes cowards of us all.
There are only the pursued, the pursuing, the busy, and the tired.
