Caring about people's opinions to the point where you lose who you are is just draining. Which is why you've just stopped.
It's a part of human nature to want to be liked and accepted by others. People constantly want to belong somewhere and unfortunately, they are willing to do anything to be a part of some group. We allow others to tell us that who we are is not good enough. We are always compared to someone who seems to be doing relatively better and then we start to feel like something is wrong with us. It usually takes a hard knock in life for us to finally realize that on our own, we are good enough.
But for you, now you just don't give a f***. You know who you are and are confident in the beliefs and values that you have inculcated in yourself. You don't believe in allowing someone to determine your self-worth and you definitely don't feel like changing yourself to belong somewhere is worth it. And that is not the only thing you do.
You don't take shit from anyone. You are who you are because you chose to be that way. You don't let anyone tell you that you're not good enough for anything and if they try to force you to do something you don't want to do, you shut them down.
You're the kind of person who has formed their belief system not out of thin air, but after experiencing various things that led you to it. You are confident in what you believe and if you see something happening that goes against it, you don't hesitate to stop it. You prefer to have healthy debates than sit and silently watch something happen that you consider an injustice. You are honest about what you believe in and proudly support it.
You dislike people who think they're entitled just because they are in a position of power or have money. Even if someone is abusing their superior role, you don't like when they look down on others and treat them with disrespect. Whether it's a stranger or someone close to you, if you find them being unjustifiably judgmental, you immediately bring them back down to earth and put them in their place.
You despise drama because you find that it's just a waste of time. You find it useless because you have to deal with reading between the lines which end up in a constant back and forth where at the end, the conversation still leads to nowhere. You also get annoyed when people complain about things without looking for a solution first. That kind of drama just distracts you from doing more productive things with your time so you shut it down when you feel like you're being sucked into it.
You have your reasons for doing things and you don't know why everyone seems to expect that you justify your actions. You are doing it for you and as long as no one else is involved, you don't need to explain anything to anyone. You know that if you start trying to justify yourself, it will only make people think that you care about what they think, which is not true.
Since you don't have to worry about what other people think or expect of you, you have the time to do a little self-care. You know that pampering yourself once in a while will make you feel at peace and content with your life. While you may occasionally compromise on your time to help someone you love, you will never sacrifice alone time that makes you happy.
People will say or do anything in order to make sure that others aren't disappointed in them. But you don't bother with pleasing people because you know that as long as you are satisfied with yourself, you will never feel like you are unworthy because they aren't happy with you.
Looking for someone's approval can have a bad impact on your self-esteem which is why you don't look for it. You know that you are a smart and talented person who is capable of being independent. You are proud of the person you are and are confident in your ability to make lemonade out of the lemons life gives you.
Hearing people badmouth others, especially those who don't deserve it and especially behind their back, can get your blood boiling. You prefer honesty above everything and would rather the person hear it from you directly than spread rumors about it. When you hear someone being nasty about another person, you don't hesitate to halt that flow of conversation because you know what they're doing isn't right.
Not caring about what others think doesn't equate you to someone who is uncaring, which is what most people think. You know that your loved ones know how you are and can take it. Most importantly they know you love them because you show them through actions. You just don't tolerate bullshit and prefer to educate those who are willing to come out of their fog of ignorance.
