There are days I don't feel like doing sh!t either, so I attempt to give my full effort into accomplishing not doing sh!t. Sometimes I achieve success!
In my opinion, it simply a matter that for so many years, through school and then from work, we've been engrained to believe that we 'NEED' to accomplish things every day. And now that we're retired, we still lug that baggage along with us. However, in my view, we 'accomplished' in school, then we 'accomplished' at work, and now in retirement we don't 'NEED' to accomplish anything. All we 'NEED' to do now in retirement is enjoy life!!!
That said, if an emergency arises or something of great urgency, I'll take care of it. Otherwise, things get done as needed, according to my timetable, but not just because I feel that I need to accomplish something.
It's been working fine for me for almost 5 years!!! YMMV
