In no particular order:
I am a programmer, with a preference for Ruby.
I am a practicing, studying, teaching nidan in isshinryu karate.
I also hold a rank of shodan in muso shinden ryu iaido, and have studied other styles such as jigen ryu, omori ryu, okuiai.
I studied Ch’iang Shan Pa Kua Chang for a little over a year.
And these are only the ones I’ve formally studied.
As far as physical, mental and spiritual development, I am a strong believer that there’s only one mountain, and many paths up. Of course, no one is holding you back from making your own path – but remember that it’s a ton more work
