I don't remember perfectly, but the creator of Lodash (javascript library) had something like a 365 day streak of coding everyday. But it was broken because he committed late a night and the cutoff was on a different timezone. He was so bothered by it, he contacted GitHub to fix it for him.

My experience is different here.

Every time when I am about to lose a streak, I would try hard not to be influenced emotionally, and would regard an opportunity to keep my ego in check. I have lost streaks many times, 50+ maybe three times, 100+ one time, and I still feel fine with myself.

Normally I would practice Duolingo in the morning before coffee everyday, like a ritual.
