I thought the point was to empty your cup as much as possible. Martial arts are more a distillation process then a process of accumulation. What is the point of learning thousands of techniques (adding to your cup) if you cannot see through to the heart of the matter? I see people all the time jumping from one art to the other without gathering sufficient mastery in any one art. This piecemeal approach is due to the impatience and laziness of the times. People often stop practicing an art, after the first stage of training, gathering. Then they're off to gather some more techniques from a different art, and so on and so on. No one is interested in the tedious process of distillation, mastery. Of analyzing the various Shihonage (for example) they have learned in order to see the underlying principles of a category of techniques. So instead of continually trying to fill your cup, with this or that technique, why don't you distill what you have until you reach the essence of the art. That way you don't have to concern yourself with any situation because you have the empirical formula for which all the formals (techniques) are derived.
IMHO of course.
