Realize it’s not always about you. No one after awhile really cares what you look like, but more about who you are and how you act. So learn to develop a well-balanced likeable personality, one which projects and reflects the true you.
Become conscientious on how you come across and communicate with others. This includes how you live, the way you walk and talk, all which makes up your character.
What a great personality does is states who you are, how others perceive you, this in the long run.
