Where do you even start?
You've been stuck in this endless loop of tabs for hours, and you can't even remember what you were doing. Is it the 17th iteration of cat videos or the 37th attempt at solving that one puzzle? You're not sure, but you're not moving on until you've watched them all.
You've got a deadline to meet, but you keep getting sidetracked by shiny objects. A bird outside the window, a coworker's gossip, or a new email from that one friend who always has the most interesting cat pictures. Where do you draw the line between work and procrastination?
Maybe you should just take a break and play some cat video games?
