Life, it turns out, goes on. There is no cosmic rule that grants you immunity from the details just because you have come face-to-face with a catastrophe. The garbage can still overflow, the bills arrive in the mail, telemarketers, interrupt dinner.
When you finally start to write something, do not let yourself stop...even when you are convinced it's the worst garbage ever. This is the biggest caveat for beginning writers. Instead, force yourself to finish what you began, and THEN go back and edit it.
