The real "crush" comes with the weight of harsh reality.
It's hard to know how to proceed with an office crush. But to start, get that lovey-dovey stuff out of your head. You have to think long-term. Before you go striking out and looking stupid, just remember that you will be seeing this person all day, every day, possibly for many years into the future.
Besides, however you think you act when you're around them, it's likely much more awkward than that. Thankfully, Fast Company has released another helpful workplace video to show what you REALLY sound like around your office crush.
Spoiler alert: Not good.
