Think of an acquaintance of yours, she may be a quite girl in your math class or a new neighbor who moved into your neighborhood. Now think about their lives you probably realize that you don’t know them very well which should make you realize you have no right to judge them. I know you have heard this many many times but what I want to point out is about you! Since you know its not right to judge others then you must realize its also not right for others to judge you.
What you should concentrate in is finding yourself. So do what ever the hell you want and dont care how you look to others because unless someone knows you as well as you know yourself its not okay to judge then the only persons opinion of you that should matter is your own and its the one worth listening to.
