I'm trying to shift my habits around myself. Going from the problem/solution perspective, my problem is that I need to work in time for my startup around my dayjob hours. If I wait until evening to work on startup, I'm already tired and it's conflicting with life stuff. So I'm trying to have at least two hours a day before dayjob starts. The blocker is that I often just drone late at night, surfing/shopping or watching tv. It's not productive time. So I'm kind of forcing myself to go to bed early, 11pm at the latest, and using a silent alarm (Fitbit Force) to get myself up and avoid the snooze button. The hardest part has been dealing with when life forces me to stay up late anyway, not breaking the habit.
