The Secret to Innovation...

 The secret to innovation...

...is to tackle a very specific problem. Obsessively, deeply, and excellently. 

Given the vastness of human knowledge already, there probably isn't much low-hanging fruit of discovery in most areas (the circle isn't uniform as depicted, so it may be lower in some areas than others). So innovation needs depth. 

Specific innovations and deep understandings of specific problems can possibly evolve into broad truths or innovations. But you are less likely to go deep and innovate if you are starting off broad. 

Notes

1. There's a valid counterargument that broad knowledge across domains can help spark innovation through a general understanding of the world and by translating ideas from one domain to another. I have a center in the middle to represent a broad understanding. It's possible that 2 or 3 areas of focus might be better than 1, but I doubt 10 areas of focus (is that even focus?) is better than 1. 

2. This was inspired by listening to CEO of Anthropic talk about how he obsessed and tinkered with the problem of speech recognition for years and that led to a more general AI. 

3. The illustration was inspired by Matt Might's excellent visual of what a Ph.D. is.
