If you think you can do it, you can.

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

Be gentle to all and stern with yourself.

You never know what motivates you.

Quality is not an act, it is a habit.

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

If you're going through hell, keep going.

What you do today can improve all your tomorrows.

Always desire to learn something useful.
