Interviewer: “You could give the world one lesson, what would it be?”
Speaker: “What you’re not changing, you’re choosing.”
Interviewer: “Hmm.”
Speaker: “For example, if you hate your body but keep the same habits, you’re choosing the result.”
Interviewer: “Wow. Yeah. Mhm.”
Speaker: “And relationships too. You can work on yourself, communicate, do your part, but you can’t change someone else.”
Interviewer: “Right.”
Speaker: “And if they keep doing the same thing and you keep staying, eventually, you’re choosing that too.”
