I'm glad you appreciate the value of a healthy, balanced lifestyle. But reading this, it's easy to see why people post "Die Techie Scum" stickers around SF. You've taken a job that someone else could actually use to help pay rent and have turned it into a hobby. If I did this job for a living I would be furious at the arrogance of someone treating as an exercise in "Feeling Good". Get some perspective.
Is it wrong of me to mow my own yard? Is it wrong of me to not eat out every day? Is it wrong of me to check the selection at the local Goodwill before buying clothes new? Is it wrong of me to not donate what I earn above the median to charity (or alternately, to not spend that amount on buying frivolous-to-me low-skill things)?
