The prevailing frame of thought in the startup community is that you have to work crazy hours if you work for a startup. If you are the founder of a startup, you hours need to be even crazier.
There a very few contrarians to this 80+ hour work week thinking.
One of them is the co-founder of 37signals David Heinemeier Hansson. I think every entrepreneur should regularly read the content created by both David and his co-founder Jason Fried. They provide a contrarian perspective to almost every pervasive startup meme you could think of.
In the particular post I want to share today titled All or Something, David makes the case for the 10 or 20 hour startup work week. He states:
The marginal value of the last hour put into a business idea is usually much less than the first. The world is full of ideas that can be executed with 10 to 20 hours per week, let alone 40. The number of projects that are truly impossible unless you put in 80 or 120 hours per week are vanishingly small by comparison.
