The book is based on an "80/20 rule" (assumption/theory/principle/"law")
that 80% results are result of 20% of efforts.
So to achieve a business or personal growth,
the first step is to identify what 20% efforts contribute to 80% results
and "let go" everything else, focus on doing "less but better".
That requires assuming "new identity" of focus on excellence
and delegating or discontinuing all other activity.
When this math is correct, the result is is "exponential growth".
The book presents many examples of various "entrepreneurs" following this path and "succeeding."
Some examples are questionable.
While written by a psychologist, there is not much insight on struggles and failures of this process, though. Also the data about success rate, and negative "side effects" of such efforts would be interesting. While well written book, it could be much shorter, there not much new info.

than it is to make it 10 percent better
Because when you’re working to make things 10 percent better, you inevitably focus on the existing tools and assumptions, and on building on top of an existing solution that many people have already spent a lot of time thinking about. Such incremental progress is driven by extra effort, extra money, and extra resources. It’s tempting to feel improving things this way means we’re being good soldiers, with the grit and perseverance to continue where others may have failed -- but most of the time we find ourselves stuck in the same old slog. But when you aim for a 10x gain, you lean instead on bravery and creativity -- the kind that, literally and metaphorically, can put a man on the moon.
