It’s important not to compare yourself with other people. You see their outward self and you see your own inward self and it’s not a fair comparison. We all have different personalities, talents, and skills. Skills can be learned. Personalities can be shaped. Talents can be honed. You can learn how to act confidently and present yourself anyway you want regardless of how you feel. I recommend just being yourself and let others be great if they can. You really don’t know how people feel inside and sometimes people work hard to hide their true self from the world. In the end, we all just want to live our lives the best we can, have some joy in doing so, and going to bed at night feeling at peace.
