It is frustrating rejection is a normal part of life, but it’s impossible to know why you got rejected

It is so frustrating because there are so many unique experiences that can be experienced for a short time only for it to become inaccessible forever. I got cut from high school’s football and lacrosse teams, and I never was told why I got denied. I tried out each twice, and for whatever reason, I never got selected. In college, I got denied by the engineering clubs and fraternities. They never told me why I was denied, and they don’t care I got denied. It is so frustrating
