Be extremely intentional today about doing a "complete shutdown" at the end of the day so you can fully recharge this weekend. If you have a pre-vacation shutdown routine, do that.
If not, here are some ideas:
Look at your calendar, inbox, and master task list. Select the major things you want to tackle on Monday morning and prioritize them.
At the end of the day, declare your “shutdown complete” and try not to look at work items all weekend. Try to fully recharge and occupy your mind with other things - family, sports, being outdoors - so you can come in on Monday morning and crush it.
