I retired at 63 but wished I hadn't. Life did not feel meaningful and I was without purpose. I did all the things I had promised myself, so some of them made me happy, which is what you have asked: I went to South Africa on a guided tour and had a mini-safari. I did every adult ed class I was remotely interested in; French, photography, art, yoga, pilates. I did my house up from top to bottom and sold it and moved to the coast. I did up the new house.
I run a retirees group which in normal times meets up for lunches with speaker, and go on trips - only 3 lunches and 2 or 3 trips, but that suits everyone. . I continue to do art classes from time to time as I find it therapeutic - better for me than meditation, which I find irritating. I also go to a journaling group one afternoon a week, which we have continued via a Whatsapp group during lockdown.
I wanted to join U3A but our local one was full, I may try again shortly.
Frankly I still feel tad purposeless, but the above are some things I enjoyed, hope some ideas are useful.
I LOVE not having or needing a purpose. A character in Ursula le Guin's wizard of Earthsea series says about Ged, the protagonist "He is done with doing. He goes home."
That's me. Done with doing.
