My schedule have this priority: day job - startup - sleep - fun.(besides programming)

Day job - 8 hours on weekday

Startup - 3 hours on weekday, 6 hours on weekend (minimum)

Sleep - 6 hours

Fun - unrestricted as long as I get my minimum hours for startup and sleep

Prioritizing works better for me rather than a schedule. I usually work on the startup longer but if anyone invites me to hangout No problem as long as I get my minimum hours.
