If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
Quality is not an act, it is a habit.
I can, therefore I am.
It's always too early to quit.
Never complain and never explain.
The dog that trots about finds a bone.
You never know what motivates you.
To know oneself, one should assert oneself.
You only stop learning when you quit.
