It's always too early to quit.
You never know what motivates you.
If you think you can do it, you can.
After a storm comes a calm.
The dog that trots about finds a bone.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
The most effective way to do it, is to do it.
Well done is better than well said.
There's only one thing that can guarantee our failure, and that's if we quit.
