Never complain and never explain.
Wherever you are - be all there.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
Well done is better than well said.
Be kind whenever possible. It is always possible.
Do not weep do not wax indignant. Understand.
I can, therefore I am.
Know or listen to those who know.
The dog that trots about finds a bone.
Words of wisdom are spoken by children at least as often as scientists.
