The wise does at once what the fool does at last.
After a storm comes a calm.
Without hard work, nothing grows but weeds.
Begin to be now what you will be hereafter.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
If you're going through hell, keep going.
You never know what motivates you.
Always desire to learn something useful.
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.
