I feel great crossing things off of my to do list, but I think I might feel better seeing a list of what I have actually accomplished. I have always had a to-do list a mile long, but that can get discouraging. For every item you cross off-you tend to add one or two more items to be done. Just looking at my to-do list can make me feel anxious, overwhelmed and tired.
Because your "done" list is a list of your accomplishments, it shows progress. Looking at it will encourage you to push ahead and add more to your list.
You already schedule important things such as doctor and dental visits ~ and they get done. Maybe scheduling grocery shopping, laundry and other projects you need to accomplish will help you get them done in a timely manner. I know that I have days where I spend to much time playing on my phone, and then I end up rushing through the rest of my day. If I time blocked just a small portion of my morning, I could enjoy these things without feeling guilty.
Bottom line - the only things that matter are the things that you actually do. It takes just as much time to write your "done" list as it does to cross things off your your to do list.
Just Remember, It always seems impossible until it's DONE!
