How do you guys adjust to getting older?

I don't mean the self-enforced sedentary and lack of fitness due to being lazy, not prioritising health and giving into getting older but rather, the lack of feeling relevant. I have found my 30's completely and utterly tedious tbh. Life is life; one day rolls to the next that is fine but just the self-perception of getting older and hitting middle age is brutal. Also when it comes to connections it feels unless you make connections by a certain stage you're pretty much dust.
