What shall become of our beloved Harry Potter after Hogwarts, or more appropriately, after the Wizarding War? So far we've been presented with three different theories: Minister of Magic, Auror, or Defense Against the Dark Arts teacher.
Minister of Magic
Minister of Magic would be Harry's least likely choice for a profession. The Ministry has always been his "allied foe," if you will, throughout the books. It was only recently that the Ministry started believing Harry, and judging by Harry's reaction, he was not pleased with them. I think that to Harry, becoming Minister of Magic would be like becoming a traitor of sorts, and he wouldn't subject himself to the rules and regulations that he's despised for so long.
Defense Against the Dark Arts teacher
Harry is naturally attracted to trouble, danger, and adventure. A sedentary position as a teacher would not be something that Harry would find himself liking. While he loves DADA as a class itself, why not get into a field where you would actually
use the lessons learned? This leads me to the final theory.
Auror
This is what Harry wants to be. This job has it all: danger, freedom, action... Simply put, everything that Harry is pulled towards. Of course, Harry was never that articulate in Potions, and Slughorn's lesser requirements made it easy for Harry to get into the Advanced Potions class (quite the scheme old Dumbledore pulled, I must say). But my problem with that lies in the fact that Harry would have done pretty atrociously if it weren't for the Half-Blood Prince. I mean, where would he have been if he hadn't of received that book? Or even if he didn't have the book, where would he have been if Hermione decided not to take that class? Hopefully he's not as bad at Potions as he let on- that 5 years of Snape just made him a little sluggish and he'll soon be a whiz .
See, Harry did get an E on his O.W.L. exam for Potions, but his performance the rest of the year wasn't too spectacular. Snape was only making sure that the best of the best, the capable people, were in his class. In a job like being an Auror, you can't do awesome 1/10 times, if you get what I mean. I don't know, from an educator's perspective I would say that Harry doesn't have it when it comes to Potions, but from my real perspective, I think an Auror would be the choice job for Mr. Potter.
