It's always too early to quit.
Well done is better than well said.
Wherever you are - be all there.
The dog that trots about finds a bone.
Only the educated are free.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.
