Poor grades in senior two. My mother asked me to learn Sanda so that I could go to college in the future. Want to know if you won't get hurt if you are tired of learning Sanda? What's the prospect?
Practicing martial arts is very tiring and easy to get hurt, and the prospect is not very good. You can exercise and hone your will. Many universities have taekwondo teams. If you have basic knowledge of Sanda, you can go to college. You can practice, but it's no use for you to continue your study. The key is school and major. Even if your grades are not good, you can go to a junior college, learn a skill and get a diploma.
