This is very similar to my routine. 6am I lay in bed going over emails (my co-founders are GMT -6 while I am in the UK so most emails come in over night for me) so I don't wake my other half. 7.30am ish I'm at my desk till noon. If it's a gym day then I'll be out till 2pm, otherwise I tend to only take 15 mins for lunch. Conference calls at 3-5 every week day, I then take an hour or so for dinner and then work till 10 or 11 at night. Sat/Sun I tend to work 2pm till 6 and then a couple of hours in the evening. When I worked for big companies I was a proper 9 on the dot, organise my day so I got out at 5 or 5.30 on the dot and drop work thinking like a heavy coat as soon as I was out the door. It's amazing what believing in what you do can do for your mental reserves though. The hardest part is convincing my partner that it's how it has to be for a while.
