To know oneself, one should assert oneself.

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

I can, therefore I am.

If you think you can do it, you can.

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

You never know what motivates you.

Always desire to learn something useful.

The dog that trots about finds a bone.

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