I can, therefore I am.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.

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

After a storm comes a calm.

Without hard work, nothing grows but weeds.

Know or listen to those who know.

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

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