Strike a balance between cool and happy on monday and see if you can pull it off all day long. If you get it down, you'll have a couple of days to enjoy it quietly before the mojo really starts to pay off. Everything will seem a little fuzzy, but you'll feel on top of it for the most part. Your people will think they know better than you later in the week, but you should just let them carry on with their business while you make your moves. You'll know what's best for everyone and can make it happen on sunday.
