Never complain and never explain.
After a storm comes a calm.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
The dog that trots about finds a bone.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
Well done is better than well said.
Quality is not an act, it is a habit.
Thought is the original source of all wealth, all success, all material gain, all great discoveries and inventions, and of all achievement.
Do not trust to the cheering, for those persons would shout as much if you and I were going to be hanged.
