I've loved every day of my 25 year retirement and don't miss stresses of work in the slightest. In the early years I did up various properties, and reshaped the gardens too before moving on and now settling down.
I've enjoyed growing fruit, flowers and veg, reading, walking, fostered a couple of dogs, renovated pieces of furniture, some carpentry, enjoyed visiting and watching the [4] grandchildren grow up.
Most of all is being able to plan days around the weather, taking advantage of good days to go out somewhere nice or potter in the garden, and then enjoy rainy, blustery or bitterly cold days indoors doing puzzles, knitting, painting etc. I've a beautiful canary [not caged during the day] who brightens every day no matter what the weather too.
The freedom is priceless: to get up when I like, do what I like, go where I like and see who I want, in my own timetable, answerable to no one. I feel lucky and my health is good so I feel blessed [so far].
