I Can't Find Satisfaction In My Awards

Hello. I've won several trophies in Tae Kwon Do for getting a new belt after passing the tests, won a trophy for mathematics, and a trophy for winning a basketball championship. I've gotten several academic awards. Those trophies/awards don't mean anything to me. I see my friends winning stuff, but I am not content with what I've won.

I really want to win something that I personally wanted to do, not something my parents put me in. A few years ago, I was considering putting one of my model aircraft I built and painted in a modeling competition, but I never got to do that. I was confident in my plane, but didn't go to the competition. Partially because of more experienced people who would win instead of me. I'm afraid of failure.

My goal now is to win a big R/C car championship. I bought a pretty expensive nitro R/C short-course truck, and I race it every day. It's been 3 weeks since I've bought it. For once, I don't feel confident in winning a R/C competition. I don't feel good enough. I really want motivation to go to some smaller R/C races and practice more. I don't know what to do! I really want to be proud of something for once! But there's way better drivers than me. They can handle a R/C car better than I can. I don't want to be disappointed when I don't win.

Any advice?
