Iin..? weird habit.

Ok, so this is a really weird thing I do. I've looked around the net and I can't find anyone else who does this. Well, I do this thing where I...race myself. In my head. And I get mad if I "lose" the "races." Say I'm listening to a song, and washing the dishes. Without realizing it, I rush myself to finish whatever dish I'm washing before a certain part of the song plays/the song finishes. It's weird. It's not always songs though. It can be anything. Like I'll be on the bus and I have to untangle my headphones before the bus makes its first stop. Does that make sense? I hope so. Does anyone else do this? Is it a mental disorder? Help me.
