Perform.
The "beginner passion" is just the excitement of learning something new. The brain releases dopamine and serotonin when you accomplish things, and the beginner phase of anything new has a lot of novel accomplishments. The further along you go, the fewer novel accomplishments there.
However, performing will always get the juices flowing - assuming the performer is fully engaging in the performance and not just phoning it in. There is also a lot more to learn when it comes to performing.
Another thing to try is a different branch of magic. When I started I was all about card magic. After two and a half years I was getting bored with that, so I branched out into other classic magic stuff like linking rings and chop cup, then settled into Bizarre magic, which quickly lead to hypnosis and mentalism.
