You are what you are, or "be yourself" etc. are very attractive mottos. Good thing about them is they are right.
Genetics, and other DNA-fundas apart, you are unique. There are no two ways about it. So if you are thinking something, there is a very minuscule possibility that someone else is thinking "exactly" that. So is there a reason behind getting "approval"? No. Approvals only make us feel good for a short time but on a long term you feel compromised. We can take millions of examples where people who created something went against the popular opinion.
So there it is. Wide open and staring at your face. You are unique. period. No one, not even your closest friends, can come close to knowing what you are. So enjoy this life being true to yourself.
