Brennan, congratulations! It is well deserved. I've had a lot of success selling a book, but now it is time to make the switch to recurring revenue.
They both have their places. You can budget against recurring revenue - it generally just takes time to ramp up. Infoproducts require constant tending (marketing), but when life happens and you need some cash, you can run a sale. Also - mailing lists glue it all together - best decision ever.
So Brennan, how did you start your mailing list, and how do you keep it healthy and growing? For example, do you allow your subscribers to post to the list, or is it just a newsletter?
Also, have there ever been times when you've wanted to hold back some secret sauce and not share it because it's just too darn good?
