What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Leap, and the net will appear.
If you're going through hell, keep going.
Either you run the day or the day runs you.
Quality is not an act, it is a habit.
If you can dream it, you can do it.
Well done is better than well said.
Know or listen to those who know.
You never know what motivates you.
In those early years in New York when I was a stranger in a big city, it was the companionship and later friendship which I was offered in the Linnean Society that was the most important thing in my life.
