One of the great pioneers in personal success and development was Napoleon Hill (1883 -1970). He authored many classic books such as "Think and Grow Rich" that continues to inspire people to this very day. He is also attributed to many great quotes including the one below which has been translated into Italian:

If you cannot do great things, do small things in a great way.
Se non puoi fare grande cose, fai piccole cose in modo grandioso.
Napoleon Hill
