The way I take up space is by unapologetically doing it what I enjoy, dressing how I enjoy, going where I want, reacting to things how I want (like moving my body to music in public), and speaking my mind honestly.
I've found when I do that, not only do I enjoy life, but people like being around me because everyone wants to spend time with someone who's enjoying life. But I have boundaries. Sometimes I like my alone time.
