 Your to-do list is never going to end. There's always going to be more things that you can add on there and more things to fill up and take up your time. How I used to think about this is that before I go to sleep I need to do as much as I can and I need to take off as many of these things as possible. But I've completely changed my thinking around that. My priorities now are to do the most urgent tasks and the things that I can do within that day. If I leave a couple of things on my to-do list it's okay, the gods aren't gonna come down and strike me with lightning or whatever. I'm just gonna do them tomorrow and that's fine. Learning to control myself and my urge to complete all of the tasks that are on my to-do list and all the things that I told myself I was going to do in that day has helped me lead a much more happy and relaxed life.
