You don't need so much stuff! At 53 years older my house is just full of stuff.
I need to trust that if I haven't used it in two years I don't need it and to get rid of it!
Also - if you can afford it - buy quality but buy once. I have a load of crappy stuff that nobody (including me) wants - and not good enough for the charity shop - but I can't bear to put it in landfill.
