Are you mining dopamine to carry you through uninteresting tasks? Dopamining is an ADHD cornerstone.
Have you had the same special interests for a long time?
Do you have a collection of interests on rotation?

I usually have a big "passion" that I keep for at leaste a few years. Right now I'm doing lots of music, and it's not that I want to do something else, it's that sometimes there's just natural dip in activity.
