Obsessionist
A person who can't keep their focus for more than a few minutes, and always switches to the next shiny thing, even if it means pissing all over the old one.
Just finished my third tattoo. Now I'm obsessed with podcasting. Next week, it's going to be knitting. I swear, I'll be a monk by next year.
I dated a guy for a month. Then I fell in love with a video game. Now I'm in a relationship with a cat. Life is chaos.
I bought a gym membership. I went to the gym twice. Now I'm into crypto. I don't even know what a stock is.
