I've lost a lot of friends and recognize that life is way too short to not be putting as much time as possible toward something you find totally compelling. The stock answer is contentment and "happiness."
The most content person I've ever met was a flower cart man in Belmopan, Belize. Probably made $100 a week at most. He knew all he wanted to do was bring beautiful flowers to people and give them a smile. He had a point in life. Sure he had kids, but he knew that they would move on one day and do their own thing, and he wanted to be known as the best flower man in Belize so he got up early to start and worked late.
This pervasive idea that "it's just a fucking job" is ultimately a milquetoast cop-out. Spend your hours doing something that has impact to you.
