You don’t need a whole lot of stuff to effectively run a household. Beware of those giving away things. You may once in while happen upon a real gem of something that can be an asset to your home. But, more likely it’s things that was cluttering up another home before it found it’s way to your front door.
Stuff can grow and before you know it your whole day is spent taking care of the stuff. I don’t go full on minimalism but I do think there is a valid point behind it. Just be careful. Before you decide to keep the whole box of stuff that someone blessed you with really look over it and ask yourself if you seriously can benefit from this being in your home. If the answer is no then leave it in the box and pass it to someone else.
Another thing you should do on a fairly regular basis is have a look at the things that currently reside in your home.
Is it an asset?
Is it just collecting dust?
If it is not bringing something to your life to make it better then consider adding it to the give away box.
