Started in October, spending about 1 day a week. Then we did a big push over the last 10 days.
Thanks for replying!
Another question is, what motivated you to start this effort in the first place? And why do you think it's useful. I haven't read the book, so not really sure
Mostly an experiment. I wanted to get a concrete idea about whether it's possible to make a living producing digital products like these (and whether I could do it :)). I don't have that answer yet (too early), but now I have some evidence that something like this can sell.
