Sounds like a great plan. You are a head because you did not fall back from not practicing. After training for 12 years. I still worked on the basics everyday.I have been working on the curriculum for my next two tests. There are a few things I want to have modeled for me in person (not just by someone in a YouTube video), so I'm trying not to get too far ahead of myself. I do tend to get carried away with enthusiasm and geek out when I'm excited about something, so it's requiring some effort to hold back.
In the meantime, I've been focusing more on establishing a regular training regimen to improve my strength and flexibility, so I'll be able to improve my technique while still learning the foundations. I want to be ready to execute the more advanced moves when I get to them, since there's no point learning fancy kicks if you're too weak or stiff to actually do them.
That's my thought process at this stage, anyway.
We have rebreakable plastic boards at the dojang; I think it'll be a few years before I work my way up to the black ones!
Breaking
I am sure your fiends have told you
The safest for hand is a palm strike or hammer fist. Even better use your elbow. Unless requirement don't do a knife hand.
