It's always too early to quit.
The dog that trots about finds a bone.
If you're going through hell, keep going.
After a storm comes a calm.
You never know what motivates you.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
Well done is better than well said.
To make our way, we must have firm resolve, persistence, tenacity. We must gear ourselves to work hard all the way. We can never let up.
