HaHa, very good! The twisting of definitions into their opposite, a very nice moment of irritation! Thank you, I enjoyed it very much. I would add and agree with you that idleness has a good sister, namely the energy of creation, which balances out with it. Without a phase of creating, any idleness would not be a pleasure. Being lazy for ten hours turns into the opposite: into stress. But I would still leave the term laziness in its negative connotation, after you have used it for this wonderful purpose of irritation, and reinstate leisure as a term. Laziness is indeed understood negatively and certainly means the hours spent completely dissatisfied and at odds with oneself, with one's own conscience constantly intruding and completely spoiling one's time. All things end so that others can begin. And so on.

Best regards!
