I have never had a day 1 on a day when I didn't have to work.
well then, Sinderos, in that case you already have proven to yourself that having day 1 be a workday makes no difference, since clearly that didn't work out so well for you.
so clearly there's no reason to think a day at work is a "better" day one than a day off work.
any day is an equally good one.
and today is the best day!
