I used to be awful at receiving critical feedback or anything I perceived as rejection. I was so bad at it that it led me to quit things I otherwise enjoyed. I went to musical theater camp as a middle schooler and got turned down for big parts for two summers, so I quit. As a dance team member in high school, I had to hear about how I could improve on a regular basis, so I quit. The pattern pervaded pretty much all aspects of my life for years.
