Love this. You had me at the first header.

I relate ALOT to this, having broadly diversified my passions and areas of learning over the years. There's something to the "jack of all trades, master of none" at SOME level - yet, there's also another level - which geniuses like Leonardo and the great Renassaince men have tapped into - where such diversity opens up the perception to a completely different form of mastery, in the ability to perceive and understand the interconnection between multiple fields of endeavour, art, science, knowledge, etc...

Such diversity expands capacity for systems thinking.

Even if not achieving absolute mastery in one of those fields, versatility opens up an entirely different skill set of adaptability and abilities to make connections between interrelated arenas, whereas masters of a single field cannot.

And as we've emerged into a global economy and face times of such rapid, massive transformation - these types of skills are priceless. Being able to understand a lot of things about a lot of things and how they all tie in together is a priceless asset than specialization in one subject cannot compete with. Both have their place. Yet the value of specialized knowledge alone could well be expected to rapidly decrease, with the advance of AI. (i.e. IBM's Watson computer changing fields of medical care and legal - blockchain & smart contracts also threatening the law society's survival). We don't need to be experts when we've got Google. But we do need creative capacities to adapt to the changing world, which can only be developed through education, exploration, and play in a diverse range of schools of thoughts, activities, and communities with different perspectives...
