When I was in high school and college, one of the things that I battled with constantly was the idea that I wasn’t “good enough”. I battled this in almost every area of my life. I saw myself as decent, but not great at pretty much everything. The things that I did care about (sports for example) I worked my tail off to become great. But I never saw myself as arriving at greatness.
Nowhere was this more true than with the opposite sex. I was constantly in the friend zone with the girls that I liked. I thought I was physically not attractive enough. Later I thought I wasn’t making enough money. The list goes on. One of my go to thoughts was, “I’m just not good enough.”
