(Or a week in the life, if a day is too small a sample size to be particularly meaningful..)
How much time do you devote to coding, marketing, sales, support, biz dev, modifying your website?
How many hours a day do you spend working?
How many hours a day do you spend on recreation?
These are fascinating questions to many of us.
Some background, the 4 of us lived in a house together and took turns cooking meals to reduce expenditure/downtime from eating out all the time. So commute time was a matter of going downstairs. We started off on 'work all the time and take reasonable breaks' for 6 days a week. We burned out really quick on that so we switched to 60hr weeks of flex-time (honor-based work anyday you feel like, send status updates to the team before clocking-out with what you did that day and just get 60hrs in a week)
With the latter schedule: M-F, I would wake up around 11a, have lunch (or cook if it was my turn), work till dinner time, have dinner, then work till maybe 2-3a. After I finished working, I would unwind with a tv/book/games before bed and then hit the sack.
Interspersed would be small breaks/small meetings (maybe an hr or so total of time a day)/phone-calls as well as goofing off on hackernews or reading blogs.
Weekends, unless I was behind on hours, I tended to spend on purely recreation or, if I was feeling the urge to code still, on experimental projects.
In addition, we shared answering customer feedback since we wanted to make sure everyone had at least a little direct interaction with customers. If divided evenly, this took maybe 20-40min a day of everyone's time.
Keep in mind even the "coder founders" were drawn into bizdev/conferences/etc. based on what they felt like attending. Nothing was really off-limits to anyone on the team, it was more about just dividing up priorities to let people get into the zone.
