If you really, really love it, then you put the work in and get better at it. In fact, I’m sure you’re amazing at gymnastics, just have a little self-doubt. It all really comes down to if you love it. I quit gymnastics about 2 years ago, and that was only because I didn’t like it very much. I now do ballet, which I love so, so much. So, I can’t really make this decision for you, since I don’t know your real feelings towards the sport, and if you like competing. Good luck!
