Obsessionist
A human being with so many obsessions they can't even remember their own name half the time.
I have 12 obsessions right now. I might have to get a second brain to hold them all.
I'm obsessed with cooking, then I got into fashion, then I joined a dance class. I have no idea who I am anymore.
I started a band. I left the band. I started a podcast. I left the podcast. I now have a pet iguana. I don't know what I'm doing.
