Amazing post - I have been a big believer of charlie munger's horizontal thinking and your post got me excited.
A few points are to mull over are
- if you are a disbeliever and someone else brings in data based evidence, learn to trust it
- one of my biggest learnings is that the less gifted but passionate like billy beane - the extraordinarily gifted seldom make good analysts or coaches because the pieces come together so effortlessly for them
- making the change and wiating for it to yield results is the tougheest part of the process - people want fruits to be borne out as soon as they water the plants. How do you assess progress without seeeing the fruits of it is something no one has figured out completely. But like ian cassel says "if you are doing better than what you were two years back, you are on track" and not necessarily doing better than your perceived competitors. That's the tough part.
good effort !
