There will come a time when you will see an opening during sparring and you'll throw a punch or a kick and it will go right where you intended it to go, just as you intended it to land; but it will happen because you have thrown that punch of kick hundreds or thousands of times until it seems as natural as swatting a fly or reaching for a kitchen utensil. It will be in your 'bag of tricks' and you can call upon it anytime you need it. But until you do it over and over and over again, knowing the movement is not the same as applying the movement.
This is so helpful for my exact dilemma. I'm not considering quitting at all, but sparring is what I've become discouraged with at 6 weeks. This is a practical way of understanding how improvement may occur - thank you!
