Don't build in the evening. In the evening, wind down the day, have a beer and plan out how you're going to use two hours in the morning tomorrow most effectively. Set one clear goal. Then... 1) Go to sleep 2) Wake up early (I recommend 6am) 3) Do the work you thought up last night I find myself remarkably productive in this cycle. If you've planned well, you'll whiz through the tasks. Focus on "doing one thing" each…
Both myself and my other technical partner switched to mornings and would never go back, this after having been a night person for 15 years.
Not quite to the MVP phase yet though unfortunately...but getting there!
Another huge benefit that the morning has over working in the evening is that you can drink coffee to get you going...if you're into that sort of thing.
