To know oneself, one should assert oneself.

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

Only the educated are free.

I can, therefore I am.

If you've got a talent, protect it.

It's always too early to quit.

Do not weep do not wax indignant. Understand.

Problems are not stop signs, they are guidelines.

What you do today can improve all your tomorrows.
