Without hard work, nothing grows but weeds.
Know or listen to those who know.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
Either you run the day or the day runs you.
If you think you can do it, you can.
Who seeks shall find.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Science is a differential equation. Religion is a boundary condition.
