I've recently taken up taekwondo again. I've going from ITF to WT and I could keep my red belt from ITF in the classes. But I have noticed myself that I am not that tough that I wish I should be with that grade. I flinch, I avoid getting hit and I feel that I perform very sloppy techniques than what is required to my grade. By "tough", I don't mean like a badass like we see in the action movies or series, but like that I could take a hit or a kick, then go in for another one without withdrawing from the opponent. This really start to make be a bit demotivated to continue. I really love martial art, but I feel I maybe expect to much by myself? Do someone of you have some tips how I can improve myself?
