how do i stop caring so much about what people think?

[The Devils troll]

I used to care constantly about everything people thought about me (sometimes i still do), but when people say that you are wierd take it as a compliment say "thanks". One because everyone is wierd/unique and if you weren't life would be boring and two because it surprises them and makes them shutup. When in public just remember not everyone notices you/knows you so just think why would they talk about you. Just do what you want not what others want you to do. What im saying may sound fake, but it works i stopped listening to other people and now i grew out my hair (im a guy and no im not gay) people told me to cut it, i refused for awile so now noone bugs me because they know i will not care. Trust me on this(even though im a kid).
