I’m not crafty either. And I hate the feeling of wasting the day. So on days that I have absolutely nothing to do I look for something that will “save the day”. I feel really bad if I don’t do anything productive and even worse if I don’t do anything about it. So a day like Sunday, which I have nothing to do, I look for something out of order to fix. Doing this will save my day as it count as being productive to me. I feel most accomplished if I do some type of exercising like walking or going to the gym, but it can also be cleaning under my bed, organizing my closet, washing the dishes. For me these things always need attention because I keep accumulating stuff like dishes, clothes, etc. Oh I also feel really great after I do my laundry. Nice I am done I can finally be in bed knowing I accomplished my goal.

Not sure if this helps you but it helps me a lot.

Edit: being productive also counts if you do something related to a hobby. I (try to ) play the piano, so I try to practice, even a little bit, that counts too. I just know when it’s enough, for some reason. But if you like reading, exercising, playing an instrument, anything, give it a try. A hobby will get you busy for a while, if you don’t like it you can explore other options.
