Roller Coaster? Slightly

I feel like I'm on a roller coaster. The reality of University in the fall is slowly dawning on me. It is incredibly exciting and at the same time is nerve-wracking. I've already picked my courses! I know the day, the time, the length, the name, everything.

I have no idea what to expect. It's just going to be SO different from High school. I think that's a good thing.
It'll take some getting used to.

I don't know where we're going
I just know we're going together
And this'll be the journey of a lifetime
I can tell already
So let's go, let's go, let's go wherever you want to take me
Take me, take me, wherever you want to
And I know that there's no going back, no going back.
No we're going forward.
