I feel the same as , I am currently still "working" on the aftermath of building a house, moving, kitchen renovation – in the final stretch quite a few things piled up and for the next 1-2 years I will have to make sure that the "everyday finances" stabilize properly again. That's why I try to avoid "unnecessary" expenses.
Consumption, or rather "luxury" in this context, would be anything beyond the necessary for me. If I have 10 sweaters in the closet and that's enough to wear, and I buy the eleventh... then that is dispensable and therefore luxury. Some consumption/luxury is still justified though, e.g. the winter holiday with the kids.
