Erwan: Actually I don't see the difference. I see what you are saying, I see what you THINK my motives are, but I feel you don't have enough basis to judge me on these things.
I still have a day job because I would like to be able to provide for a family, put children through school and give them a suitable life without much difficulty in a financial way. Ask someone who have an ample amount of money what their focus is and ask someone who has inadequate funds what their focus is, one has to worry how to pay the bills, one can concentrate on what they WANT to do.
Aside form that, if it were just me, I would train all day, learning, exploring, exploring and expanding my boundaries and helping to lead other people to do the same thing (you can't show someone their boundaries, only help them find it themselves).
So, I don't "Use" parkour in the way you think I do, I want to live it, I want it to be my life. However I do have the intention of raising a family which does cost money, so if I am to do both, then it does require monetary income.
I will not be a monk in a temple, dedicating my life only to myself and my practice and then helping others, but instead will do that as much as I can while having a family.
Anyone who knows anything about the cost of opening and running a business will know that this is a total loss for me in terms of money, even if the DVD sells 1,000 copies, which I can guaranty it won't. The T-shirts are a total loss for me, and take up my time when I'd rather be training. The website takes my time and money, when I'd rather be training. However, I DO FEEL that these things benefit people, and therefore I do them. I also enjoy them because I feel they benefit people. Otherwise, I could make a stencil and make myself one T-shirt and be done.
Yes, I hope that someday this will be a positive cashflow, just as David and Co must if they want to maintain a parkour gym. One can not eat good intentions or sleep under the comfort of helping others. Definitely colleges do not take good will as payment.
So, while I do feel I understand what you are saying, I don't agree in your assessment that I am so different.
When I did martial arts seriously (now I only "dabble") I was in the dojo 6 days a week for 3 hours a day, I lived it, I taught it, and the school made money form my efforts, and people gained benefits in their life from my efforts.
This is my wish with Parkour, so if there is still something you see as different, please help me to see it, I am trying to be open to what you are saying.
