I should answer a few things:
1. This is possible because I sell products. I don't do consulting and haven't for over a year. My products will continue to sell even when I'm not working like crazy to create new ones.
2. I live in Boise, Idaho which is not very expensive. I could live quite comfortably on $80,000 per year. In Q1 2014 I made $140,000, so I'm not exactly hurting for money. If I hadn't purchased a house last week, my bank account would have plenty in it. This is not a risky financial move.
3. The consulting example was just a story I heard from a friend. That's not me, I don't do consulting. Being able to do something like this is another reason I like selling products even better.
4. This would not be possible without the great team I have in place to run ConvertKit. While it still takes my time (and I really enjoy it) they handle all the support and serious issues.
Anyway, hope that clears a few things up. Thanks again for all the kind words and attention.
