Remember the last scene of Harry Potter and the Chamber of Secrets, when Harry was talking with Dumbledore? Harry admitted he was put in Gryffindor just because he told the Sorting Hat not to put him in Slytherin, even if the Hat was telling him he would be a perfect fit in that house.
Dumbledore told Harry that in the end, the Sorting Hat agreed because that was where Harry himself decided where he wants to be. Sure he ended up fighting a basilisk and facing the world's most evil wizard but he came through right?
I'm here where I am right now not because of fate or circumstance, not because of skill or how good or bad I am, but ultimately, inevitably because I choose to be here. Now, at this moment, at this second, I have to choose whether to stay or to move on.
Which would be the better choice then? At this point, no one can really tell. Honestly, who can say it would be good for me if I stay? Or I'd be better off if I leave? And anyway it's still my choice to make and my mistake to face, if ever.
