It ok to feel that way. Learning a new Martial art is not easy and may not always be fun. My opinion is, you should try something new or stick with it. When I first start training Taekwondo , I didn't like it at all. Intill I tried other things, like wrestling , Boxing and kickboxing. I experimented different martrial arts to see what suited me. I think it would be a good benfit to learn a little bit of everything!!..right?
I went back to Taekwondo , and soon it became my love, and I then looked forward in learning new kicks.. To make it clearer for you, I am just saying just because your good at math it doesn't mean you'll love history.
