Leo Babauta, author of ZenHabits, shares how he conducts his business, now one of the most trusted and read blogs in existence.

I don't understand what he charges for:

Make money by helping. I put out products and courses that I think will really help people, and that’s how I make money. This works really well for me. People are happy because their lives are better, and I’m happy because the revenue I make is entirely coming from making people’s lives better. We both win, our lives are all enriched. This is not the case from advertising (see next item).
