It's always a possibility that interests may change. As we grow and have different experiences we find new things that attract us or lose interest in things that have become less so. It's impossible to predict where your passion will ultimately lie. It's important to keep checking in with yourself and also to give yourself the opportunity to grow.
If you are committed to keeping an interest, though, then take actions to protect it. Set aside time for it, continue to learn and grow, and continue to make it a priority. Sometimes we drift away from the things we love because we don't give them the nurturing that they need.
Whatever happens I hope you find your path and your happiness. Good luck!
