I don't know what I am doing

I am 15 yr old boy in 9th grade and I am confused as hell for my life.

At first I wanted to be a professional chess players than lost interest in chess , then got interest in track and field and hot to know that I am not the best in it, then started playing badminton and realized I am not the best in that too.

I am just confused as I get average grades in school and I have always been passionate in going to a good college but I know I am not the best!

And I live in a place where there are almost no sports training places and I learner all of the sports by myself so I don't even know where I stand

don't know what to do and confused as hell for my career and future

help me if you can!
