Let me try as I think I am almost your opposite.

Hour 0-0.5: get back to whatever I left the previous day... most productive 0.5 hour of the day with a fresh mind.

Hour 0.5-1.5: meetings, status updates, syncing with others...

Hour 1.5-3.0: more intense coding. May be bug hunting, new feature, more testing...

Hour 3.0-4.0: lunch.

Hour 4.0-5.0: typically helping other team members or discussing bugs/new features etc. Or doing "research", keeping up-to-date reading whatever (software related), including HN.

Hour 5.0-5.5: coffee break, thinking about personal stuff usually, have a little snack or something.

Hour 5.5-7.0: more coding. Much lower productivity though, typically leave things to finish in the 0.5 hour I am most productive the next day. Might read news and non-work related things to give my brain a little break every now and then.

Interesting! Thank you for responding.

What's striking to me is that if we break it down, it seems like for you by category it'd be:

Hard task/"brain" time: 2-3.5 hours depending on that last section

Light task time (including wakeup time): 2-3 hours

"Active availability" time: ~1 hour?

Personal time: 1.5 hours

and for me by category it'd be:

Hard task/"brain" time: ~2.5 hours depending on my after-lunch section

Light task time (including wakeup time): 3 hours

"Active availability" but not working time: 1 hour

Personal time: 1 hour

So even though it's distributed differently, the amount of time we spend on the types of tasks are pretty similar.

I do the hardest thing first thing in the morning, that fresh zest.

If I'm not feeling it (motivation) will try blasting music/getting pumped then start to slowly get into the flow. Usually works.

I have the similar schedule like you do. I even plan a short 0.5 - 1h training between morning and lunch. And like you, I am more productive in the afternoon, at the end of the day.
