I don't know if it counts as a sacrifice but a few years ago I had to abandon/give away over 90% of my belongings because I was taking a plane to another country to live a new life and could only logistically bring what I could carry on my back and in two suitcases (one for each arm). Almost everything I'd accumulated from clothes, to books, to tools, to furniture and all the little good-for-nothing items (i.e. memorabilia, etc.) over several years was left behind. Felt sad as I was packing all my shit, it took a few days, but when it was over I quickly forgot about it and felt a certain lightness to my existence that was wholesome, and relieving. It was a shock to remember just how useless a lot of the things we carry around are, or how easily it is to start over with close to nothing.
