To know oneself, one should assert oneself.

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

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

The dog that trots about finds a bone.

It's always too early to quit.

Be gentle to all and stern with yourself.

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

Expect problems and eat them for breakfast.

Either you run the day or the day runs you.
