Bertoldo de Giovanni is a name even the most enthusiastic lover of art is unlikely to recognize. He was the pupil of Donatello, the greatest sculptor of his time, and he was the teacher of Michelangelo, the greatest sculptor of all time. Michelangelo was only 14 years old when he came to Bertoldo, but it was already obvious that he was enormously gifted. Bertoldo was wise enough to realize that gifted people are often tempted to coast rather than to grow, and therefore he kept trying to pressure his young prodigy to work seriously at his art.
One day he came into the studio to find Michelangelo toying with a piece of sculpture far beneath his abilities. Bertoldo grabbed a hammer, stomped across the room, and smashed the work into tiny pieces, shouting this unforgettable message, "Michelangelo, talent is cheap; dedication is costly"
If you want to be your best for God then you should try to find ways to use your gifts in an effective manner. In other words, perhaps it is best to serve God in areas were you are sure of your strengths.
