Came here to read the comments because I often feel the same way, but realized that I don't think attitude is the main problem, to me that's a symptom.

In my case, I have a lot of anxiety and perfectionism, probably undiagnosed adhd, that always gives me intrusive thoughts about what I should be doing at all times. Talking to a therapist and my partner more openly about what I expect from myself has opened my eyes to how screwed my perception is.

I'm now working on being nicer to myself, saying to myself that I did a full day of work and cooked a meal, great adulting, now I DESERVE to chill. I still need to confirm that with my partner frequently, who happily tells me to stop being ridiculous and go play.

Other things that have helped me recently are going to bed and waking up early (thanks to my new puppy) and reflecting on different activities using this concept.
