yes, but if trying not to be wasteful creates an anxiety, then you need to treat the anxiety first. in that case giving yourself permission to be wasteful is what matters, and responding to that by telling to person not to be wasteful is counterproductive.

No, that’s just the wrong way to think about it. It’s something that needs doing, so you do it. Are you anxious about going to the toilet? You’re not. You do it as it’s necessary.

Sometimes it helps to stop thinking and start doing. I’ve been there. It takes practice.
