I've found letting go of some things to be hard, but it's sooooooo nice to have some clearing going on too. I've been watching "Clean House" and I've learned some tips from them although I do find that they MAKE people get rid of some things that it would be "ok" to keep--such as pieces of NICER furniture. My house is nowhere near the houses they show on Clean House so I'm luckier there!!
Letting go is sometimes about more than letting go of things, it's also about letting go of some memories and some people. That's the really hard thing. There are some people I've needed to back away from for my own peace of mind and health. Not all things and people are good for you, just like anything that is edible is not always good for you. And of course, you don't have to give them up for good, just back away for a while and re-evaluate and then taste/see them in small but good quality ways. I let go of my "career" when I retired--and let go of a lot of people there, but I do see SOME of them occasionally. I've found a new wonderful career for myself now, that I love and cherish. So change IS good!! VIVA LA CHANGE!!!!!
