Know or listen to those who know.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
Leave the atom alone.
