Some beginners want to collect forms. Instead of learning one form thoroughly, they want to accumulate.
As a consequence, superficial knowledge is sought, and the beginner never penetrates the art.
Collecting forms and drills is not a good thing. It leads to an attitude of flitting.
The untrained mind becomes goal-oriented and skips around.
By doing more, we accomplish less. Do not spread yourself too thinly.
Thinning our time and our attention leads to a watered-down outcome, rather than a richer one.
