But I strongly recommend you dig deeper in your TKD journey. I think you will find there is a lot really good stuff to discover out there.
I'm sure there is, but to be honest, my preferences go more towards passing on the official curriculum without wanting to add anything to it (or remove anything from it). I feel there's more than enough in current KKW curriculum to keep our classes busy and students minds full.
This shows the difference between passing on the system and your "personal journey".
To instruct, to be a teacher - that's where pretty much sticking to the official curriculum is good. You're passing the system to a group.
Deeper delving is a personal thing imo, it doesn't really have much of a place in normal open lessons because (as stated) they're full enough with the official stuff.
There can be crossover, you can seek further information from your instructor, and your students can do likewise with you.
If even a tenth of the stuff I personally research was covered in class I'd bet 90% of the students would leave and/or there just wouldn't be time for the fundamentals, let alone normal development. There's stuff that I've dug up that my instructors have no inkling of (and more than likely more in the other direction).
And this kinda leads into where the whole 'purpose of forms/patterns' thing comes in as well. Anything over and above what is "in the book" is for the individual to discover.
The instructor should show you the form, explain the basics of interpretation and help with your development - but not to just try to insert all the possible meanings into your head.
What works for them is unlikely to work for you, or me, and is it really possible for any one person to have all the answers anyway?
Put simply, you can't break down and decide every movement and expect a single coherent outcome - you more need to feel the movement and find where you can use it, or not. That's not something an instructor or a bunch of random internet people can do for you.
