I can, therefore I am.

Quality is not an act, it is a habit.

If you're going through hell, keep going.

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

Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

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

The dog that trots about finds a bone.

If you think you can do it, you can.
