I have a quote from David on my office wall. It says, "You have more to do than you can possibly do. You just need to feel good about your choices."Get comfortable with the idea that your lists won't be down to zero until the day you die.
I remember when I first read it. It was so affirming to realize it wasn't ever going to get it ALL done.
The review is key. Acceptance of the fact that there's just too much is also key.
