Sure, I train Ch'ang Hon ITF style.
I got my first kub in 2000, but I got bored, so I stopped in 2001. In 2004 I picked it up again.
When I returned lots had changed, our school was changing from 'style' or bond. So when I returned I had to learn the 'sine-wave' and other stuff, but my siter got her 1st dan, so that's why I HAD to get it too haha. (she started doing taekwon-do at the age of 14, I started when I was 7
When I returned I wasn't that fanatic, I trained once or twice a week, sometimes I didn't train for a whole month....
But I became Dutch Tuls Champion in 2005, while I wasn't training a lot, so that got me motivated to do more.
Turning 18 also made me think it would be a good age to get my 1st dan.
I have my 1st dan since May 28th.
So technically I could have been 1st dan waaay earlier (not as fast as you got your 2nd kub), but I'm glad about the way it went.
Ok... you didn't ask for my life story sorry
