I've known for a long time that being yourself is the way to go. But the way that Oscar Wilde, the famous Irish poet and playwright, put it is probably the best reason ever to simply be yourself. What's the point of trying to be someone else? It's already been done. Embrace what makes you unique, even if it makes people stare at you funny.
Just share this quote with them as your reasoning for being so beautifully (and at times awkwardly unique). Some of them may actually take this quote to heart and they'll thank you someday for it. Or they'll totally forget where they heard it and benefit without your knowledge. Pay it forward, folks.
