I agree with you about moralizing - it can be (and often is) harmful. But in this case the advice is sound. Taking care of your stuff, not discarding it just because it is a bit worn around the edges, and trying to repair it instead of just discarding + buying new; is there something wrong with this approach? not sure it is a &quot;single best thing&quot;, but it would make a difference. A large one imho.
