To know oneself, one should assert oneself.

Know or listen to those who know.

Never complain and never explain.

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

Either you run the day or the day runs you.

It's always too early to quit.

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

If you've got a talent, protect it.

Without hard work, nothing grows but weeds.
