I can, therefore I am.

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.

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

To know oneself, one should assert oneself.

If you think you can do it, you can.

Wherever you are - be all there.

Without hard work, nothing grows but weeds.
