It's always too early to quit.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Know or listen to those who know.
After a storm comes a calm.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
The most effective way to do it, is to do it.
Only the educated are free.
I once went to one of those parties where everyone throws their car keys into the middle of the room. I don't know who got my moped, but I drove that Peugeot for years.
