Things do not happen. Things are made to happen.

The secret of getting ahead is getting started.

It's always too early to quit.

If you think you can do it, you can.

To be a good loser is to learn how to win.

The wise does at once what the fool does at last.

Be gentle to all and stern with yourself.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.
