I've been on a few teams now with daily standups, first thing in the morning. Always feels weird to me and like most days I have disappointing result to report - all because I tend to work kind of burstily.
Like, I might go days without any progress to show in terms of code building. Then, one day I show up with a half-dozen pull requests from a bout of hyperfocus after the gears in my head have had awhile to turn.
If you take my productivity over a month, maybe it looks about average. But, it comes in lurches and long spans of wheel-spinning in between.
