Be original and unique. Don't try to be someone else. You would never act exact like the original does. And actually nobody wants to have a copy of himself. And people are even noticing instinctively, if you are authentic or not.
Just be authentic, be the BEST YOU, love yourself and be original. It is the way to success. Look at famous people out there, they are all originals. Special and unique in their own way. If they would just copy someone else, we would recognize it and wouldn't like it instinctively.
