People only change when they feel like changing for themselves and not necessarily because of your efforts. And so trying to make someone else change or wishing that they would change, that's not where your power is.
My sincere advice, don't put your time and energy there because you might end up being disappointed. Instead, let someone reveal who they are. Because when you stop giving power to things that aren't in your control, guess what you get at time? Energy, power, confidence, peace, and joy. And when you let them be who they are, you're not letting them do anything to you. You're letting them reveal exactly who they are through their behavior.
And you should always remind yourself that you always have power because you can leave any date. You can leave any relationship anytime you choose. So you can hold the belief that
people can change. And at the same time live in the reality of who they actually are now.
