What is one thing - just one thing - that I can do that will make tomorrow easier?
It makes a great start to the week if I can go in feeling caught up or even just a little ahead on the game. Something that takes me 30-45 minutes on a quiet Sunday will take me an hour or more while I'm in the office, by the time I do it in between all the other things that need to be done. So I can take the 30-45 minutes on a Sunday, and I can walk into the office Monday morning knowing that one item on my list is already checked off.
It's not for every weekend, and it's not for every person, but when you know you're going into a busy week, taking a little time on Sunday can be the difference that tips you from "overwhelmed" into "busy but can handle it." Enjoy your weekend. And use your weekend to help you enjoy your week.
