Quality is not an act, it is a habit.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
To know oneself, one should assert oneself.
Leap, and the net will appear.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Be kind whenever possible. It is always possible.
What you do today can improve all your tomorrows.
Be thine own palace, or the world's thy jail.
I love the wry motto of the Paleontological Society, meant both literally and figuratively, for hammers are the main tool of our trade: Frango ut patefaciam - I break in order to reveal.
