You are right: it could still work as something I enjoy. It is just that I am in a state of my life where I do not want to put too much time into such an activity: I have a greater desire to create things that people want. But I still watch interesting movies and occasionally it could be joyful to solve a math problem. But as I do not watch movies dozens of hours weekly, I also do not want to solve math problems dozens of hours weekly. This has probably to do where I am in life currently. This may change later in life (I am middle aged.)
