To know oneself, one should assert oneself.

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

What you do today can improve all your tomorrows.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.

Know or listen to those who know.

You never know what motivates you.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.
