I have the same experience. Until 30 I was one of those people who schedules every hour of their life, used habit trackers religiously, set SMART goals and recorded metrics of how I spent time. I got settled financially/professionally/personally and over the past few years have dropped the old productivity methods. This year I decided to drop the last of them entirely, with great results. Focusing on the moment at hand and following my instincts has made me a lot happier so far, and is still leading to great opportunities.

Maybe it works because we kept our heads down until we were settled, and loosened up after gaining enough experience to develop good instincts? Interesting to hear someone else has taken a similar path with similar results!
