One of Michelangelo’s greatest masterpieces was his sculpture of David. He worked on it with such passion that he often slept in his clothes, resenting the time it took to take them off and put them on again. He made hundreds of sketches of possible attitudes and detailed drawings from models. He tested his ideas over and over in wax on a small scale and only when he was satisfied did he pick up his chisel. He approached the painting of the Sistine Chapel with the same intensity. For four years he literally sweated in physical distress but look at what he produced!
Martin Luther King said, “If a man is called to be a street sweeper he should sweep the streets as Michelangelo painted. He should sweep the streets so well that all the hosts of heaven and earth will pause and say, ‘Here lived a great sweeper who did his job well.'”
If you are not passionate about what you do, find something you can be passionate about! Always give your best effort. Don’t strive to make money, strive to make a difference. Significance should be your goal, not survival.
