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

I can, therefore I am.

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

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.
