Self-fulfilling failures
One of my best friends from high school has a brother who is three years older than us, his name is Cade. Cade has a friend named Tanner, and they both played basketball for our high school until they were juniors. Both of them were extremely good. Not necessarily because they practiced all the time, but because they loved the game and I mean they really loved playing basketball. This made them very passionate about the sport which made them really good at it. However, they never actually got to play in any games; the coach would put in 8th and 9th graders in (in a varsity game) before he would allow them playing time. They got so mad about it they ended up not going out for basketball their senior year. They decided they would never have a chance of playing so why go out for it? They looked at not playing during games as a failure and told themselves they would never get to, so that was a self-fulfilling failure for them both. They could have gone out and still had fun with their teammates and had fun at practice. However, the chose to miss out on their senior year (and last time to play in high school) of basketball all because of a self-fulfilling failure.
