It's Saturday night here and am enjoying web development instead of partying.
Is this adulthood ? Am i doing right?

i never understood the enjoyment of partying. i always ask people who party: why do you party? like what did you achieve so you're partying right now?

a lot of people party like they're rich, while i study in silence like im broke

You have chosen wisely.

I mean I feel like proper adulthood is finding the needed balance between getting work done and decompressing so your brain gets time to rest and have certain "AH-HA!" moments. Since we're all different, some get it from partying others get it from curling up reading a book.

Hopefully that made some sense. So all that to say, if you took even a minute to achieve mental diffusion (diffusing in a way that makes you happy), then yea...you adulting

Adulthood is being able to take care for yourself, do stuff to keep you mentally happy and good shape, and being responsible for it

Sometimes I think alcohol and partying is a waste of brain cells, time, health, money and adds nothing of value to your life.

Other times I just fucking love to party.
