... so that's 19.23 years ...
Well, that made me sit up:
I'm practicing for 19 years, 12 weeks and 5 days now to the day.
I had 7 years with 5-6 days in the dōjō. One day was 2,5 hours. I count 5 times/week.
12 years with 3 days, 2-2,5 hours. I count 2 hours.
I'm attending seminars about once a month. Mostly Friday-Sunday, one class 2-2,5 hours plus about two times a year a five day long seminar. I did not attend a seminar during my first year.
I count 17 years,10 seminars each year, 8 hours of practice each seminar. (I think this gives a minimum value.)
I do not count the solo practice (bodywork and qi things) of about 1,5 hours each day.
This sums up to 9654
hours of practice.
Only 346 hours to go until I reach mastery!
Even if I don't attend any seminar with my teacher or our shihan anymore I will reach mastery in about 1.11 years!
