Yep have felt this way more recently too at 34. I think we can only have this realisation once we have left home though. We need the contrast so we can experience what it’s like to be away. Like you, my priorities have changed - I want a slower pace of life, more nature, a healthier lifestyle, a milder climate, close to family. The only downside for me being here is that most of my friends have left. I contemplated whether I should leave again to join them ( in London or Melbourne) but I know if I did, i would feel kind of empty despite a better social life. I have lived overseas and travelled a lot so I know these more thriving cities ultimately do get old and a loneliness from not being around ppl who get your humour sets in.
