You are perfectly cast in your own life. I can't imagine anyone but you in the role. Go play!
: Lin-Manuel Miranda

I feel like everyone needs this reminder, you are you and no one else can be or ever will be (unless you are cloned but usually clones turn out evil so even then) you are one of a kind and completely unique. Even if someone is almost identical to you, in personality and looks, there is always going to be a few things different that make you you because the things we experience in life shape who we are and no one experiences the exact same things the exact same way. So when people say you are completely unique and one of a kind and you think you aren't just know that it's almost scientifically impossible for two people to be identical in personality so yes you actually are one of a kind, and we love for it!
