Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

If you think you can do it, you can.

It's always too early to quit.

The most effective way to do it, is to do it.

Quality is not an act, it is a habit.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

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