You are simply here to please your self and not other people. You can't be free, you can't express yourself because you always think that a lot of eyes were watching you. You think that they are judging you, belittling you, mad at you and laughing at you. It is important to know that you are here to satisfy yourself and do what you wanted to do regardless of what people may say.
Let me remind you again that the sun can explode anytime, you can die anytime so if you are not yet living your life to the fullest because you're so afraid of what people might say then you're totally wasting your life.
Just get what you want, do what you want, say what you want. Don't be scared of fucking up and embarrassing yourself. You can make decisions for yourself and nothing can stop you doing what you wanted to do.
You can take the last shot even if your coach will get mad at you if you miss. You can pursue your real dreams even if your parents will get mad at you because you are not yet earning money. You can make weird arts even if people will call you weird, weirdness is fun, it's a lot of freedom so you better try it. As long as you're not hurting anybody by following your true feelings then it is alright.
You may hurt someone unintentionally by being yourself too much but it is their fault because they were too sensitive. Sensitivity leads to poverty, being emotional will make anyone go hysterical. Just always stay cool and let your emotions come and go. Don't fight it, don't follow it if it is negative. Just be yourself and you can experience real freedom. Detached yourself from the outcome and expectations from people.
