How to be yourself without being arrogant?

[OttmanDiouri]

Ive had many confidence and self concious problems in the past. Now i fully understand the concept of not caring what people think of you and to be yourself if you want to be confident. But my problem is that when i try to let go of peoples oppinions of me so that i can just speak confidently and be myself, i end up comming off as somewhat arrogant. Does that mean that arrogance is part of my true personality? Because sometimes no matter how hard i try to just not care and be myself despite of what others think, i end up acting arrogant. Why is that? I hate this.
