Indeed, there are times that you do care what others say, especially when it comes to people who love you. Still, you never let those opinions affect you when deciding or acting. Because it is true that when we care too much about what other people think, we allow ourselves to be carried away by fear and try to understand what it is that we are doing wrong. But that is not a problem that affects you, Aquarius. You do not care at all what people have to say about you, so you are always free to live your way.
In addition, another thing that makes you such an influential person is that you treat others equally and do not judge if you do not know them. You don't want people to suffer the same as you do not. You don't want them to have to listen to criticism or opinions that the only thing they would do is affect them. You are aware of how much prejudice can be accepted by a person. At that moment, when you have to give an opinion or make a criticism, you do it politely and constructively.
