How your body just seem to fall apart...
Realizing that after you've wasted resources on what you intended to lead to a career, you must now re-evaluate and make a new plan
Even living with 5 siblings did not prepare me for how utterly disgusting, stubborn and disrespectful housemates can be.
Not me per se, but many, many people.
Your youth is a very automatic stream of progress, you get older, you graduate classes, you eventually finish school, study something, learn a trade etc.
Once that is over, many people (At my age especially) feel overwhelmed from the fact that auto-progression is over now and that this motivator is gone.
I'm not even suggesting that this means you need to set your sights on advancing your career further and further (The most miserable people I know are the ones that focused heavily on career) but that you need to learn to deal with that fact, in whichever way works for you.
That just because people get older, it doesn't mean they have matured.
Having younger people ask for advice and realising that I'm actually the adult in the room. Scary.
Dealing with the death of family members. There is *SO* much to do it's really a daunting prospect and the first time, you literally have no idea where to start.
Nobody sets up my appointments with dentist. I have to bring this doom upon myself.
Having to work so much. Where did all my free time go ;-;
Spent my late 20's constantly worried about getting older. I'm 30 now and I've stopped caring and everything feels so much better. Enjoy yourself and make the best of your time.
Friendships are extremely fragile.
Doesn't matter if you've been close for ten or more years. All it takes is a little bit of distance and maybe a change in occupation or schedule and boom, all of a sudden you haven't spoken in months.
Basically, friendships require a lot more preventative maintenance, like your car. If you want it to last, you're going to have to keep in touch and show that it means something to you. Otherwise it *will* fall apart sooner or later.
Making friends and connections without spending a fortune. As a kid you just hung out. As an adult it seems like I need to spend $60 for a monthly membership or $40 for a night out. It’s like a pay to play system.
Time somehow speeding up with no way to slow it down.
Household never stops, and if you take abreak from it, it punishes you.
