I had my first ever family Christmas vacation in December thanks to a big buffer. 2) My comic does not need to be topical, current, or hip, so there's no reason to NOT work a long ways out. 3) If I die, my estate will have sufficient lead time to hire an artist and writer, such that you might never miss an update.
