In email, the rock star is not exactly leading a mediocre life or even an average life. But it doesn't mean that you don't come in every single day and try to really do a great job at the thing that you did the day before. Is that what the rock star life is? It's not mediocre, right? It's still excellent.
Must one always strive for excellence? Is perfectionism a good thing? And can Mike have two bad days in a row?
