Yes. But then again , I 'suffer' from bouts of Eudamonia .
What is the best way to catch Eudamonia ? It's when death arrives , grabs you by the scruff of the neck and dangles you over the river Styx .... but then places you back in your life again . It's happened to me three major times * ... why am I not dead yet ?
But after just one of those experiences ... you will 'like' your life ... at least . Every day, every moment ... every blade of grass and insect and .... well, everything , is a miracle and wonder .
Also I think it has to do with the body's ability to process - including process toxins - and a good balanced internal metabolism for the healthy levels of serotonin productions and similar processes .
What will erode all that and cause confusion and dissatisfaction and eventually depression ( the opposite of eudamonia ) and high suicide rates ) is people being removed from the reason and purpose they are here ; living their True Will , fulfilling their nature , living their khvarenah . Many natural or native people naturally have this and are in this state . That is why we often observe that those without much material richness and greed seem 'innately happy ' , while many in the west that have access to all sorts of goodies and health care and recreation are depressed , in pain and have sickness .
For example, I live in one of the best pristine places , desired tourist destination ... lots of good stuff , but the local chemist has one of the highest in the state per population distribution of pain meds and anti depressants . Sydney Harbor has anti-depressants in it , that is from the residents taking so much, it passes out their bodies and into the sewerage system and the amount in the harbor is just from harbor side pipe leakage !
The other way to fall in love with your life via eudamonia is to follow and develop those things the ancient Greeks said led to it . Thing is though you would need to understand their view on the 'virtues' is different from the modern ideas (including 'virtue' itself ) . One factor that helps is having a 'tutelary spirit '
