The best way to find "introversion" (is that even a word? 🙄) is to get out of your confort zone and do stuff you aren't used to.
Well i am not the best person to say this, cuz I keep telling myself i will do it. I will engage in conversations with strangers, I will start going out more, I won't feel weirded out to go to the cinema alone, but it never happens.
Usually getting out of your confort zone is very tiring and demanding, so start to take baby steps when you approach this "out of confort" zone!
