It's always too early to quit.
Be kind whenever possible. It is always possible.
If you're going through hell, keep going.
If you think you can do it, you can.
Either you run the day or the day runs you.
By failing to prepare, you are preparing to fail.
Well done is better than well said.
What you do today can improve all your tomorrows.
Wherever you are - be all there.
Quality is not an act, it is a habit.
Modern society, based as it is on the division of labor, can be preserved only under conditions of lasting peace.
