Someone once asked...

“Hello, after few years i never being like normal dude, like, I'm keep being childish while everyone develop their adult-expression, i want to be like that, i dont want to be messy, i want succes, i want something valuable to change myself, i want to be something, like my age, everyone just know something through out kid to teenager but me? Im still wondering how human rule knows about, i want to fix myself”

Someone answered with kindness...

there's nothing inherently wrong with childish and silly every now and then, you just need to know there's a time and a place. I have noticed that for me though, i act increasingly more stupid and idiotic when I doom scroll and don't have anything of substance going on in my life. If you think this might be a contributor for you. Limit your screen time, Find a hobby to start, a skill to learn, and a subject to study. Like for instance, no more than 30 min on social media, start playing Volley ball in your area, Teach yourself to play Piano, and study the ancient roman empire. Doesn't have to exactly this, but I think this can help you grow. good luck :)
