Ask HN: What do you think about the 40+hours/week vs. work life balance debate?

Clarification:

I am not trying to start a fight here.

I am just curious about what the hackers and founders here think about this question.

Work could mean your day job, your company, your side projects, reading, studying, etc.

I am referring to the dhh vs a lot of other people ( e.g. Austen Allred ) "debate"
