@StealthNinjaMum - Yes, we definitely seem to have a lot of the same clutter issues. Tbh, I've got some more paperwork to do, but at least it's organised now.
Love the idea of the links! It's so much better to pass on bras and things than to bin them.
Another useful thing to know is that some charities will collect. I know I've mentioned it before but it really helps, especially when you first start clearing, and many people seem not to know about it.
Perhaps a list of where to let go of certain things?? Eg. Old towels and carpet squares can go to animal shelters (ours are always asking for them). Batteries can often be dropped at the supermarket, so you don't have to make a special tip run. Also, 'rags' can go to many charities - they make money from them. Just some thoughts.
Peridot - As Stealth mentioned, I've got rid of loads of cookbooks. They were all like new and I just couldn't sell them. I've got to say, I haven't missed a single one!!! I'm down to 6 smallish ones now. I use maybe 2 of these. I also have a file of my own recipes with some old faves and I use this all the time. That said, if you love them and use them, keep them!
Stealth - It turns out that olbas oil does go off. I had a newer one and could smell the difference. Tbh though, it was 11 years past its use by date!! 
Penelope - I think that's exactly what I've got to do. I'm building up to it.
Lovely to see so many new people on here. Welcome everyone!
