Elon Musk's wife calls this "Idea Sex".

> Choose one thing and become a master of it. Choose a second thing and become a master of that. When you become a master of two worlds (say, engineering and business), you can bring them together in a way that will a) introduce hot ideas to each other, so they can have idea sex and make idea babies that no one has seen before and b) create a competitive advantage because you can move between worlds, speak both languages, connect the tribes, mash the elements to spark fresh creative insight until you wake up with the epiphany that changes your life.

Nothing like another rich person coming in telling you how making money isn't the goal and not important to them. What's really important is idea sex!

"Just become a master at that one thing, and then become a master at another, and viola! Idea sex. Then you'll really be rich! lol!"

Gee, if only I had married Elon Musk.

And sooner than you think, you'll become a "Jack of all trades and master of none".
