I have learnt that peace isn’t something that just happens.

100%! Fortunately, the more we make these peace-fostering changes in our life, the easier it becomes I think, so the important thing is (as with many things) to just start.
Shopping is actually something I want to monitor and cut back on in 2025, as well. It's very easy for it to spiral out of control, and I totally relate to the feeling of having been ripped off! I hope we both manage to get a grip on that in the coming year! :D
