Regardless of whether you're a social, functioning member of society, life is HARD and sometimes you just want to lock yourself in your apartment and not interact with anyone (save for the Chinese delivery guy—you've gotta eat). The frequency that these days occur depends on how frustrating your life/job is.
But unless you're some kind of a MILLIONAIRE (and if you are, what are you so sad about? MONEY BUYS HAPPINESS, JUST ASK THE KENNEDYS), you don't have the luxury of holing up in your apartment and disconnecting with the world. You have to get out of bed. You have to get dressed. You have to open your front door and get to work. This Press Onward Doormat ($45, Izola) will be a helpful reminder to keep going.
Or, it could serve as a reminder to guests who've worn out their welcome to stop standing in the doorway of your apartment saying "goodbye" over and over again but never actually leaving.
