Do you know what happens when you decide to stop worrying about what other people might think of you? You get to dance. You get to sing. You get to laugh loudly, paint, write, and create. You get to be yourself. And you know what? Some people won't like you. Some will laugh or mock or point out flaws... but it just won't bother you all that much.
We come by agonizing over public opinion quite naturally, having been taught to be polite, bite our tongue, learn to get along etc. All of it adds up to a genuine concern about how we effect everyone else with our actions/words.
What others think about you is none of your business. Don't worry about the opinions of others. Allowing their judgments to have any effect is giving your control to them. You don't have to justify yourself to anyone, there will always be people that will go with negativity. Don't try to please everyone, it can't be done and it's a waste of time to try. Never accept someone's version of you. Just do your own thing, be yourself and enjoy your life. Set yourself free, there is no need to worry about anyone else's perspective of your lifestyle.
"Care about what other people think and you will always be their prisoner." Lao Tzu
"You'll worry less about what people think about you when you realize how seldom they do." David Foster Wallace
"I don't care what you think about me. I don't think about you at all."
