Actually, this is a very simple question but there are people fake their selves and acting like someone else. Did you know why people say you should always be your self? , There are several reasons for that, but In my point of view, I believe the following things:

1. You will be Naturally Beautiful
2. The Right People Will Love You
3. It can be Develop Self-Respect
4. It will create an Inspiration - only for others to feel inspired if your be in your own version not fake one.
5. Take Control of Your Life
6. The Real You Can Change the World

Always Be Yourself
