Though he grew to be a rich man, the interesting fact about michelangelo was that he lived in near squalor and rarely changed his clothes or even bathed. Also he was harsh on himself and his work. In one of his many letters about his work on the Sistine Chapel he famously wrote, “I am not a painter.”
He was often dissatisfied and known for his critical, volatile moods. In fact, one of his peers in study, Pietro Torrigiano, was so angry with Michelangelo for his talent — or more likely for his smart mouth — that he punched him in the nose, leaving it permanently crooked.
