"training everyday" does not mean "being on the mat everyday" or even "doing martial arts techniques everyday." Eventually the martial arts lifestyle leads to the consideration of all tasks as training.
I think "training everyday" does in fact mean to log some hours on the mat... unless you train on the grass or sand (which is fun). I usually train 6 to 12 hours a week in my dojo, and I consider myself a hobbyist. I just don't think it is a realistic attitude to take to say that martial arts is my life if I am only training for 2 to 3 hours a week, regardless of how I view other tasks.
