I feel this in my bones. You described my entire 20s. I felt pretty ashamed that I couldn't master this single skill. When I got into my thirties, I chose to embrace it instead of fight it. I worked at companies that were understanding of my chosen schedule. By every metric across the board I've been happier since then. The single exception was a period of time where I had to be up on a 7am international conference call every morning. The stress necessary to maintain that schedule was enormous, and came with consequences to my health. Never again. I just don't think humans are meant to keep to a schedule. It requires massive amounts of stress to keep up.
