Being 'myself' but getting nowhere!?

I have had a lot of school and place changes in my life. Everytime I changed my school I saw the people around me in school. Chose the group I thought was kinda popular, acted as if I was like them and very easily became their friends and then gradually their best friends. Most of the times even became the most important person of that group. But when I achieved what I wanted to achieve I felt very low and stupid. It seemed such a waste to change myself just to get friends. My suggestion would be to remain yourself and be joyful about it. If you are happy with yourself you should never change. Just show yourself friendly and you will get friends who would love you the way you are, would appreciate you and your talents and wouldn't want to change you. I am happy for you too and best of luck with your fashion designing career.
