As with most people I'm trying to cut down on the amount of 'new' stuff that I buy - partly for environmental reasons and partly for financial reasons.
I've always been pretty driven by material things - I enjoy experiences and time with family, friends and pets as much as anyone does - but I've always been a motivated consumer!
One of those people who swaps their phone every time the contract is up, very into interior design and getting things for the home. I used to spend a lot on clothes and make up but that has got better because I'm now fat so less vain
I'm trying very hard. I don't need practical tips like using Ebay, etc to buy second hand.
It's the psychological side - I talk myself into cutting down and living more simply but then see so many things I 'want' and feel like I 'need' (obviously I don't, they're not essentials).
I watch documentaries/ read books about the climate crisis and make pledges but then one day later I'm looking at hot tubs or wanting to buy new clothes for a holiday 
Has anyone become less materialistic?
