Everyone is unique. How awful would it be if everyone had the same personality and same sense of fashion as each other? I couldn't hang, that's for sure. Be yourself. You know who you are. You know what you like to do, what you like to wear, how to wear your hair, and no one can take that from you. If you follow what others are doing, then you will never know who you are and what you like and so on. Stop looking for what's cool and start getting to know yourself. Find out what you like. Find out what makes you feel good. Life is too short and too precious to be a copy.
