You just need to see that who you are is already perfectly sufficient. Fundamentally, social anxiety is seeing our true self in a distorted way and believing the distortion to be the truth. We magnify (or even flat-out imagine) our bad points. We worry about our perceived flaws, all while completely forgetting the myriad gifts we have to offer. You don’t need to co-opt someone else’s confidence when you can discover your own. All you need to grow is a willingness to try.
