Importance of competition in life

I don't feel anything, I don't compete / never had to except , I don't have a rival or such that keeps me motivated to move forward . Neither do I feel happy nor sad not angry nor frustrated I have become emotionless . Feels like I am just stuck .what should I do , does everyone go through this?? Is there a sport i should compete in?? Don't know why but I feel , competition will help me get the better out of me but at this point of life it is difficult to just join any random sport How important is it to have a rival to keep sharpening you??

Sorry for random rant
