I didn't really make a plan for what to do after retirement. Like the saying goes
"Life is what happens to you when you're making other plans." Two of the reasons I retired 25 years ago were because my health wasn't good and my mother was aging and needed more of my time. She and my husband used to tease me about being busier in retirement than when I was working. I also was baby sitter, "chauffeur" for Mama and my grandchildren, who had to get to daycare and school and sometimes even for my step children and step grandchildren.
When those responsibilities started to lessen, my husband and I began traveling...nothing fancy, just trips to visit relatives down south and our newly purchased timeshares in the Poconos (PA) and later on...Atlantic City, N.J, neither of which were in our plans.

We did timeshare exchanges a few times to go to Virginia Beach and Ocean City, MD. We also went to Baltimore, MD to visit his sons and Washington, DC . I couldn't get my husband to take a cruise but finally got to go on a 7 day cruise to Bermuda in 2019, a few months after he passed. Earlier that year I visited my honorary son in Tampa, FLA. I also spent several weeks at the AC timeshare that year, something I planned to do every year but COVID halted that plan for a couple of years. Another example of plans being altered: I had planned to do more traveling after the pandemic slowed down but now with our "new" kitten, who definitely has separation anxiety, I don't want to be gone for too many consecutive days.
Shortly after retirement in 1998, I purchased a used digital piano from my alma mater's piano sale and started composing songs, some of which wound up on my debut CD, released in 2003. I never dreamed I'd be releasing an album! After a long hiatus I released 3 songs in 2020. 1998 is also the year I met my half siblings, "new" nieces, nephews and cousins. This opened up more opportunities for family time and socialization. My current plans are to continue working on songs for my next release, hopefully by the end of summer, start spending time at the timeshare again and just enjoy all the beauty that nature has to offer that will uplift me and give me a sense of peace.
