There is no such thing as an "advanced knife fight."
...or gun fight.
...or any kind of fight.
We start out simple.
All I ask is that people I worry about is that they constantly "push their envelope," in every good way. Then someday they become very mature and smart, or well...more mature and more smart. Each day may bring a revelation of yesterday's immaturity.
You eventually get so smart, that you make revelations on the need to simplify. That is a very complicated idea, indeed!
Push the envelope... not just horizontally, but vertically also. I think that, as like the biceps will not significantly grow, unless the thigh muscles grow some also, the mind must grow on many, seemingly un-interrelated subjects.
Push your personal envelope. Sounds complicated. But it is simple really.
