For the last 3 years, every time we're working on back kicks, I've gotten a critique from my Master that I'm not bringing my knee up high enough. I couldn't really figure out why I was supposed to bring my knee up higher until just recently. Now I've made a break-through, but I have to retrain myself in both muscle memory and accuracy to make this effective. 
To elaborate on what I mean, this is how I used to do a back kick: Bring my foot up to my knee (as in crane stance) and kick the foot straight back, with my knee pointing away from my target the entire time. My Master kept telling me to bring my knee up higher in the chamber, but the way I was kicking, it actually hurt the kick.
Bringing my knee up higher on a front kick makes sense, because I'm kicking away from my body. But if I brought me knee into my chest on a back kick, now my body is in the way of the kick. (At least, that's how I saw it).
We also got criticized for bringing our shoulder around or bringing our leg up to the side, that we should be doing a back kick instead of a turning side kick.
Well, I didn't think too much of it at the time. I was just happy I wasn't doing a turning side kick. But in class on Friday, I realized that while my foot need to go straight back, my knee could rotate out a little bit, and I am not giving up what the back kick is. I tried it on BOB a few times and one of the other black belts (ironically with the same name as me) was like "wow, nice kick!"
Already, I've found this new method of kicking:

Already, I've found this new method of kicking:
- Is easier to kick around guards
- Is easier to kick at an appropriate height for Taekwondo
- Is easier to hit with the heel instead of the ball of the foot (which is what was happening)
- Fits with the spin motion better
- Delivers better power into the target
