Hi Everyone! I have finally gotten to the point of trying to get rid of some things I have been hanging on to.
These things were from parents, grandparents, other family members or just when I was much younger.
I know the saying is: if you haven't used it-get rid of it. The only trouble is some of these items are sentimental items.
I freely admit I am too emotional (can't think of right word right now-soft, etc), hope you get my drift.
I thought about keeping just 1 of some things. People have said sell it, take it to resale shop-you'll get money from it.
Well, lot of people are doing the same thing, downsizing. I can't just throw some of this away....I blame my mother, grandmother-lol.
I have asked my son "if I was to die tomorrow, what would you get rid of?". That has worked for some things, but not so much on others-lol.
Okay everyone, how did you do the downsizing...what is your secret to get rid of items that are just taking up room???
