The Onna-Musha: Japan’s Forgotten Women Warriors

History has a habit of changing its mind. Japan’s women warriors were long known in English as onna-bugeisha, but historians increasingly use the more accurate term onna-musha—women who actually fought. Discover the remarkable story of Nakano Takeko, the fearless warrior who led a band of women into one of the final battles of the samurai era, and learn how a simple change in terminology reflects a deeper understanding of Japan’s past.

The New Indie Author

What if the definition of an indie author hasn’t kept pace with the publishing industry? The principles that built the indie revolution still matter—but the world around them has changed dramatically. It’s time to rethink what independence really means in today’s publishing landscape.

All or Nothing

What does “All or Nothing” mean to you? For me, it sparked an unexpected question: has anyone actually read every single one of my books? With more than 200 titles across multiple pen names, I’m curious to know if there are any complete collectors out there. If that’s you—or you’re getting close—I’d love to hear from you.

How to Expand Your Discoverable Surface Area

Solar Sail Theory isn’t about finding stronger sources of momentum. It’s about becoming better at capturing thousands of weak sources of momentum that already exist.

One newsletter subscriber won’t change your life. One podcast appearance won’t transform your business. One new reader or conference conversation or bookstore event won’t either.

Individually, they’re almost insignificant.

That’s why the sail is enormous.

The Magic of Increments

We all know about compounding, but very few of us truly understand it. The real magic isn’t in one newsletter, one blog post, one book, or one workout. It’s in the quiet accumulation of thousands of small increments that, over time, become something far greater than the sum of their parts. Solar Sail Theory isn’t about finding a shortcut—it’s about patiently building enough sail to catch the wind that’s already there.
