I'll be honest that I'm still bitter that I didn't receive an owl to get into Hogwarts [1] (it's never too lake, J.K., it's never too late). Yes, I realize that it's a fictional school and filled with make-believe magic, but that doesn't change the fact that Hogwarts is the best wizarding school [2] in the world. Who doesn't want to learn spells and ride around on a Firebolt? And, of course, one of the greatest aspects of Hogwarts life is getting sorted into your house.
Figuring out if you truly belong in Gryffindor, Slytherin, Hufflepuff, or Ravenclaw is a job only the Sorting Hat can do. Thankfully, Pottermore [3] has the definitive quiz (proud Hufflepuff here) to get sorted, but in case you're looking for something a little more magical, this Harry Potter Sorting Hat Mug [4] ($14) will reveal your true house in a very magical way. When the mug [5] gets warm, it transforms from a simple black mug to show your shield and house emblem. What an awesome way to start your day, even if you're not an auror or working at the Ministry of Magic.
