Where were you last night? Occasionally, I take an hour-long treadmill interval class because it's fun and has lights and music. Me during the class:

I'm so fast, I'm the fastest guy in the class

So so fast

Hey, that young dude is going faster than me

Just gonna speed up a little

Yeah I'm (barely) kicking this dude's ass, this dude who doesn't even know I'm racing him

What the hell, he quit halfway through the class and I am an idiot

Gonna keep up this speed because I already committed to it

I mean, I was already planning to take today off, but this sure didn't help. My competitive brain is going to kill me someday.
