Same here. I was just like you, hitting the road almost everyday when I was a beginner. Right now, I have to work a lot, and I get home completely exhausted, so I don't feel like biking so often. Maybe 2 or 3 days in a week is what I do now, specially on the weekends.
I would have to agree that a lot of things changes when one reaches adulthood more so family life. Priorities change and leisure sport activities like cycling are set aside for work and family life. But after some time, a couple of decades lol. You would get a second chance to relive your good old hobbies.
