When I started lifting, I was in my early 20s, when I had similar goals as you and a tremendous amount of free time.

By the time I hit my “target”, life started getting busy and my free time was replaced by various obligations.

For me, the desire to continue lifting shifted from a goal body to having an hour a day that was 100% mine. Maybe that could work for you as well.

The ever-present fear of losing all your progress also helps.
