Haha yeah, my website was one such “accident”. A friend told me I should have a website, so that same afternoon I spent 3 hours on Squarespace to make a first version (which wasn’t that different from now).
My books were also “accidents”. I realized that I had produced all that content on Medium already, might has well put it in a format that’s more “accessible”.
It put them all in one day, even the 500+pages one… I was in flow from 5am to 9pm for that one.
With all the content you have already, I’m certain there are plenty of things you can do to turn it into a business. I need more dad advice from you haha!
