I can, therefore I am.

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

If you're going through hell, keep going.

If you can dream it, you can do it.

The dog that trots about finds a bone.

Be thine own palace, or the world's thy jail.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

Be gentle to all and stern with yourself.
