Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Things do not happen. Things are made to happen.
Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
Do not weep do not wax indignant. Understand.
If you think you can do it, you can.
Words of wisdom are spoken by children at least as often as scientists.
