There speaks someone who doesn't understand the crisis times of lack of confidence and the panic of thinking it's never going to come together.
You didn't need the belt. People had these problems long before coloured belts were used to denote ranks, and still have them in styles that don't use belts at all.
IMaybe I'm just crotchety but a kick is not a kick and a punch is not a punch between various arts. I have seen more people that were taught poorly or just plain old differently then were taught the same when comparing styles.
Why concentrate on the differences? For the most part, I've found people who nit-pick differences in similar techniques are missing the point. It doesn't matter if your foot is pointing "here" or over "there", so long as the end result is the other person getting hurt.
It's a testament to just how flexible these things are that there are dozens of different ways to kick and punch, all of them being effective. A punch from a boxer is going to look very different to a punch from a karateka, or a muay thai fighter, or a TKD fighter. They'll look different, but they'll all be the same in their intent, they'll be similar in their execution, and they'll be nearly identical in their results.
It doesn't matter if you kick or punch exactly the same way as your new style does. So long as you kick or punch
well.
Now, I know there are some people out there who, for whatever reason, want to learn how a particular style does something simply for the sake of learning it. In those cases, it is beneficial to forget everything you have previously learned. Myself, I am more interested in learning the best way for
me to do things, and if that means I am throwing boxing punches and BJJ takedowns in a TKD class, then that is what will happen...
