If i'm not mistaken...our friend "vaulander" is an example of someone that falls in the Positive aspect group. He seems to a geniune desire to better himself and so long as he never quits, great for him!
My take on this query is " Whatever get's you there man"
It's not really important what gets a person interested in Martial Arts. The MOST important thing is after they have found it, what kind of person do they become? Are they literally wiling to do Hard Work or not ?
I've gotten many students who all said they started in tournament style TKD...and were later happy and surprised by the depth of Trad. Kung fu.
Go figure..."whatever gets you there man ".
And about the negatives persons:
Those persons who are lazy Deuche bags and not willing to travel if they have to...or Not willing to save up some money and learn from a real teacher (not just off Youtube).
...They will always lurk in the shadows and i was hesitant to contribute for a long time. Now that i'm a little older...I don't care as much anymore. So i've personally started to open up more. But in general, Screw them! Those morons with no integrity will never prosper.
