For most people, there is no real thing that is going to be better if you are going to work one more day, or check your email on Christmas day, or take a meeting while your family is gathered for dinner.
It’s just your fear of giving away control and of finding out that you are not that important.
Take a break, go on vacation, spend quality time with your family. I promise you, when you will go back, the same problems and challenges will be there waiting for you.
You might just have some more resources to tackle them.
