What you do today can improve all your tomorrows.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
Who seeks shall find.
Leap, and the net will appear.
Well done is better than well said.
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.
