People often talk about having revelations in the shower.
My revelation time seems to be 3:00. If I am lost in my own thoughts and can’t get it together, I find that I’ll often come back to it around 3:00 and find something useful.
Today I spent almost 5 hours thrashing on a project. I felt like I was just stuck. At 3:00 I returned to it and saw what I was missing.
3:00 is my shower time.
