What I do when it gets really difficult is fill out an index card with hours (7:30, 8:30, 9:30, etc, between 48 and 72 of them) and then I just check off each hour with a pen as it passes. Sometimes I am far away from getting even to Day One, and so I count hours. I know the goal is to get away from counting ultimately, but this helps in those first couple of critical days.
Who's actually going to read this thread and vote "no"? Anyway. Time to get back on the horse. Here goes Dawn of the First Day. (72 Hours Remain)
