With age comes wisdom: At which point in your life do you OR SHOULD stop taking people and everything seriously (age, maturity)?

What and how long does it take to become a fully grown mature and wise guy?

I know that this is superficial as it can vary from person to person. Because you'd see adolescents that are like 37 and the other way around, whatsoever... but is there a rule of thumb estimate?

If you had to ask me, I'd imagine someone who stopped being needy about everything like for example:

"Omg this guy or girl is soo cool and awesome! Let's exchange numbers and hang out with him/her. He/she is so interesting" (even if... thats really nice and it could be.. why not... but no neediness anymore?)

"Oh wow I want to visit that place so bad. We have to do it somehow"

Wisdom comes from having lived and survived a full and complicated life. You have to go through hardships and suffer great loss in order to come out the other side and be able help other people get through it.

Typically the older people are, the more life experiences they've gone through and learned from, but that isn't always the case. I've known some very naive people who are even in their 50s and 60s just because they lived a very sheltered and privileged life (They were spoiled by their parents and then spoiled by their spouses). They haven't really lived. On the other hand you occasionally meet a very bright young person who's been through hell and can teach you a thing or two.

Instead of looking at people’s age, observe their actions. If you admire someone’s results, ask for advice / recommendations to obtain that result.

it really takes a life time...

but also, a life time can also be lived in shorten time, within a life time, that is

sometimes, some moments do really make you grow up, whether you intend to or not... watch out for those, Dennis

You shouldn’t. Most people are ignorant and ignorant people are dangerous. If you value your life and livelihood you should remain vigilant.
