I agree with the discussion that this isnt typical for programmers (employees) but I think for founders it is very different. A successful founder has to put in so much. Even when you arent working, you are often working -- that might mean lunch with a potential investor gatekeeper or a soft pitch to a prior colleague who might refer you to a client. Or working the room at a conference. Or speaking to a lawyer on the phone even when you're at the playground with your children...because otherwise you might lose some critical client sale in the redlining process.

I dont think I've ever worked as much as when I was a founder. There is also the sheer leverage you have over the business and outcome. Every hour invested can mean so much.
