I was working 3 days per week (12 hour days) then got Covid on March 1. I resigned 2 weeks later because I was still extremely tired and did not want to return to work. I miss the second income and am now sorely reliant on my SS check and savings. It’s doable because I have everything paid off. My monthly bills enable me to pay them and still deposit the remainder to savings. I also use CareCredit, if needed, for large purchases (vet bills, dental) that I can pay off monthly with no interest, usually within 18 months. Tip: pay EVERYTHING off before you retire.
I'm 73, and have been retired since 2015. I work to keep from becoming bored or "losing my edge".
I even taught Embedded Computing in high school for three years. I stopped that because I don't want to spend the money or time to get a certificate. The teaching was a blast. The school was unbelievably supportive of me.
