Thanks for such long comment. Ad.1) I will consider adding costs. But those are very little - hosting $30, some domains I buy and renew. Plus tax and health insurance that is specific for each country. Ad.2) It looks very interesting to flip websites based on my stats. But what really matters is the good idea that sells. And it is hardest to get plenty of such. Ad.3) She is happy that I am at home. It is harder to work like this because there are many disturbances. But it is a way better to be your own boss + in my case double the income + have a lot more free time.
