Rejection doesn't hurt because it's inherently bad. Rejection hurts because we make it hurt.
We have a specific pattern—a "default rejection pattern" that makes us feel awful after we hear "no" in any situation... dating, with friends, meeting new people, job interviews, sales, with partners, parents, family... With anyone really (even strangers on the sidewalk!)
In order to truly liberate your most free, bold, authentic self, this pattern must be eliminated.
When we do, rejection stops being so painful, and so we stop being so scared of it.
