Here’s a trick that will help every time you do it.
Work hard during the day, and cross off as many things from your list as you can. But as you’re winding down, save something. Leave one thing undone.
Don’t actually do that one more task—but do identify it. Write it down and leave it in a place you’ll see it when you settle back in for more effort.
Stop before you’re completely ready to stop.
Build a bridge to the future, and leave your current day’s work knowing what you’re going to do next.
It will help. Every time.
