It's always too early to quit.
Always desire to learn something useful.
You never know what motivates you.
Without hard work, nothing grows but weeds.
Well done is better than well said.
If you think you can do it, you can.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Who seeks shall find.
Begin to be now what you will be hereafter.
The man with the real sense of humor is the man who can put himself in the spectator's place and laugh at his own misfortune.
