If you have trouble completing dreadful mundane daily or weekly tasks and you have ADHD like me, try using a time tracker to "convince" your brain that they only take a few minutes so you're more likely to get them done!
Use this "freebie" tracker to time yourself doing things like vacuuming, dusting, washing dishes, etc. (I even timed myself giving my dogs a bath because I procrastinated it so badly! Then I realized it only took an hour to bathe all 4 big dogs so it's much easier for me to just DO IT!)
Once you've seen that it doesn't really take that long to complete the tasks at hand keep reminding yourself by saying "it will only take 3 min, 5 min, etc". Your brain will begin to realize the tasks aren't that dreadful, you'll get them done and feel super
Hope this helps you as much as it's helped me!
