Never regret. If it’s good, it’s wonderful. If it’s bad, it’s experience.
The best way to cheer yourself up is to try to cheer somebody else up.
The only real mistake is the one from which we learn nothing.
If you’re going through hell, keep going.
One may not reach the dawn save by the path of the night.
Do the thing you fear to do and keep on doing it . . . that is the quickest and surest way ever yet discovered to conquer fear.
