I'm very grateful to have reached the age when I have wrinkles, although I'm not quite as grateful for the aches and pains. I always try to remember that not only do many people have a lot worse to contend with, but that a lot of people never reach the age of wrinkles and aches.
The dust in your house doesn't appear to be any worse after about six weeks, unless, of course, someone puts their finger in it, and if you dust today, then die in the night, the dust will be just as bad tomorrow.
If you've every said "one day, I'm going to .................", then make today your "one day" because for some people it never comes.
I used to do housework every single day, but now I do it as and when I want, or not, as the case may be. If there's something more interesting to do then I do that instead. I learned from my mother who, if my dad asked her to go for a walk, or a picnic, or whatever, always said she had housework to do. My dad died when he was thirty nine, and I often think about the time wasted doing housework when they could have been together. My motto is now "Do what makes you happy and doesn't hurt anyone else".
