To know oneself, one should assert oneself.

Know or listen to those who know.

Go for it now. The future is promised to no one.

Only the educated are free.

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

Quality is not an act, it is a habit.

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

I can, therefore I am.

What you do today can improve all your tomorrows.
