Be kind whenever possible. It is always possible.

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

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.

It's always too early to quit.

If you can dream it, you can do it.

I can, therefore I am.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.
