Never complain and never explain.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Have convictions. Be friendly. Stick to your beliefs as they stick to theirs. Work as hard as they do.
My experience has been that work is almost the best way to pull oneself out of the depths.
