Never complain and never explain.
The wise does at once what the fool does at last.
Well done is better than well said.
Leap, and the net will appear.
If you're going through hell, keep going.
If you think you can do it, you can.
Either you run the day or the day runs you.
Know or listen to those who know.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
No one is so completely disenchanted with the world, or knows it so thoroughly, or is so utterly disgusted with it, that when it begins to smile upon him he does not become partially reconciled to it.
