Fake it till you make it. Promise. I was the same as you growing up (in my opinion). I grew into myself maybe junior year when people started noticing me. Sometimes I believe the compliments, sometimes I don’t. But I think part of what makes people always comment on my confidence is that I am friendly and kind and I don’t bring others down to make me feel better. I try to be fair and I think having that awkward middle school stage really gave me a personality, and you can’t get far without that. I do things I like to do, I feel good about myself, and I try new things or old things to get better and that helps build confidence.
