I was definitely happy with a structured less chaotic life. I went back to work (as a consultant though) for a year after a major financial crunch off the last startup.

Going back to a 8 hr day job helped in many ways beyond finances

-structure

- a good routine

- minimal decision making on a daily basis (I mean things like should you let go of the employee, should you buy another server or manage with the same, calling up electricity backup repair etc)

- lesser stress levels

- social activity without feeling guilty of time spent.

- broader focus. You keep yourself open for more ideas.

The only feeling that would be odd is - control & speed.

As far as the working for others is concerned, I think you got to accept it. You are in a job for a purpose, it is not as exciting and rewarding but necessary. And it does has its benefits.
