In my experience I've found that without money, it's difficult to focus on enjoying your life. When at the end of the month you don't know how to feed your family, it can become the reason why you can't sleep. In such a situation happyness is quite out of reach.

What we earn here on hive is nice but as you say, it's difficult to earn a living in a developed country here. However we are at the very beginning of blockchain related income and I believe that it has much growth potential and maybe we are having a early starter advantage that will allow us to make a reasonable income here.

In the end happyness and money are not related. Happyness depends on how you look at the world and how you can appreciate what you have and what you are. This inner wisdom I blieve can't be bought with money ;-)
