Things do not happen. Things are made to happen.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
I can, therefore I am.
The most effective way to do it, is to do it.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
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.
