I've been retired for nearly eight years now. The time has flown by, I'm having such fun. OK, the drop in income took some adjusting to but we spend far less on food (I used to be too knackered to cook and ordered far too many takeaways and convenience foods).
Best
Pottering in the garden.
Having time to cook and learning to enjoy cooking again.
The ability to take afternoon naps {smile] For about five years before I retired I'd start to really flag at about 4pm. I finished work about 6pm and those last two hours were often grim, plus the commute home.
Ditching my mobile phone which was essential for work, but not for my life. Sometimes my line manager would text me after 10pm!
Worst
Being at home for scam/spam phone calls. I never realised the sheer volume of daytime landline scammers. On a bad day there'll be six or seven between 9am and 6pm. I've even had occasional death/rape threat if I hung up and they rang back in fury at my audacity in not handing over my bank details.
