Night. I'm impressed that you refer to the different forms of happiness (laetus). It is a differentiation that many in our instant world are unaware of. the instant gratification we get from drugs, orgasms, gambling and other things is intense, brief and evidently non-existant when it goes away. Long-lasting happiness brought upon by positive mindsets, hope, love, understanding often don't attract people due to their milder potency. In my monotheistically inspired philosophy. This is the Good and the bad. the selfish and the socially conscience. The intense and brief and long and meaningful, but maybe not so intense. But yes. It's something not many know to differentiate.
I have had succesful trades with countless strangers. They all walled me firt though and never demanded that I trade first
