What job career should I go into?

I love sports and was thinking about going into Sports Management because I really wanna work with the Professional league sports like hockey/baseball/ or football. I know that this is extremely competitive business to get into so that's why I'm nervous to go... All my friends are going for good paying jobs and I don't want to be left behind because of choosing this and getting stuck with like a manager of a high school team. Otherwise I was thinking about being something in being a pediatric nurse or something that's deals with babies. That's Altot of school I know so I'm nervous to do that and not end up happy.. but i know it makes tons of money. Ialsoo hated nursing assistant classes with elders. (no offense). Then I was thinking something in business marketing/management but that's a lot to! I'm Really undecided is all I'm saying....I would love a job that keeps me finacially happy. ( no computers or science stuff)
