You never know what motivates you.

Things do not happen. Things are made to happen.

Only the educated are free.

Be gentle to all and stern with yourself.

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

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

What you do today can improve all your tomorrows.

If you think you can do it, you can.
