i don't think people really understand that there is no coming back from certain things. Some damage does not get undone, and once it changes how you see someone, that's it. Not everything deserves a second chance, no matter how sorry they are.
Be boring. Don't chase trends. Don't follow opinions. Do your own thing. Things that feels right in your heart. Wake up early. Go for walks without music. Read books that takes weeks to finish. Watch old films nobody talks about. Music that's rare. Build a private, unimpressive life that makes you deeply happy. A slow life that feels like your own. That's all that matters.
