A. I do actually write about big things too (take a look at my website).
Regarding the “small minutiae”, there is a story about Michelangelo, who was working on his statue of David when a friend asked him why it was taking so long. The artist explained that he often had to go back and straighten a line or smooth out a corner. “But these are just trifles,” said his friend. “I know,” replied Michelangelo, “But trifles add up to greatness… and greatness is no trifle!”
The moral is surely obvious.
