We all have things to do apparently. Well, it's still better to have something to do, right?
I was thinking about guilt in this context. Guilt means that we do something that is negative. But you don't. You think that you haven't done something positive, that's neutral. It's neither positive neither negative. So it does not make sense to feel guilty.
If you can do things, it will be positive, and we would be grateful. If you can't, that's neutral, it's ok.
I suppose it's rather about choosing how to organize time.
