I went "cold turkey", retiring from a very busy, responsible, and demanding job, with long hours, to an immediate "stop". It truly was the best thing I could have done, and like other posters here, I now don't know where the time goes - the hours fly by. (Admittedly I do love a lie-in.) DH is retired too, so maybe that makes a difference? My advice is that you take a walk, go window shopping, meet a friend for coffee - do whatever you enjoy and RELAX. And give yourself permission to slow down, before making any big commitments like voluntary work. Give yourself enough time to do what YOU want to do, alongside supporting your family. Wishing you a very happy retirement.
