If you're going through hell, keep going.
If you think you can do it, you can.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
After a storm comes a calm.
It's always too early to quit.
The dog that trots about finds a bone.
If you can dream it, you can do it.
Be gentle to all and stern with yourself.
Know or listen to those who know.
The darkest hour in any man's life is when he sits down to plan how to get money without earning it.
