Never complain and never explain.
Only the educated are free.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
You never know what motivates you.
Well done is better than well said.
If you're going through hell, keep going.
It's always too early to quit.
Wherever you are - be all there.
Leap, and the net will appear.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
