Who else would you be but yourself? Well, there are people who take on their mate/partners/movie stars characteristics, looks, mannerisms, etc. In my opinion these people are losing themselves.
What is more unique and beautiful than being you? Nothing! There is no one else in the world like you. You are an individual with your own thoughts and feelings, your own quirks and style.
Like the tulip in this picture, stand out on your own by being yourself because there is no one better!!!
