I started lifting weights two years ago. First time I've ever really succeeded in developing an exercise habit in 50+ years. Progress is slow. Every few weeks I can add maybe 5 lbs to a particular lift. Or maybe not. I have no specific goals. But the accumulated progress is remarkable to me. I have a better body now than I did in high school. It's still not "fun" but I do it every other day and rarely miss, and it does give me a sense of satisfaction to complete a workout.
