Leap, and the net will appear.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
It's always too early to quit.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
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.
