Too many options?

I've always heard that it's common for students who just graduated high school to be stuck in this "what now...?" mentality. As if they were focused so long on high school that now they're not exactly sure where they're going in life. Well, my situation is quite the opposite.
If I had to reflect on my entire high school career, I'd say I've learned and grown in ways I never though possible. I've developed into this woman that I can honestly say I'm proud of. Yeah, I still need work, but I'm not ashamed of who I've become. I have purpose. I have ambition. I have something to live for that is greater than myself and I have the passion to pursue that. That's a lot more than most high school students can say. But where do I start? Honestly, I have so many dreams, so many possibilities. Which do I pursue first?
There are three major things that God has put on my heart recently. Music, Photography, Global Compassion (in no particular order.)

What do I dedicate my summer to?

I've seen that I could easily be running my own photography business right now. I've already put out a project for this band with album art and photography that was well beyond the expectations of a 17 year old girl. Photography is my art. It's so much of a passion of mine and I would LOVE to do that for the rest of my life.

Next is my music. Worship. That's my life. I've felt this calling towards starting a band that, rather than focusing on playing a service every week we act like a band that's separate from any specific church service and can focus on the creative side. Like writing our own music, touring, etc. That's been a dream of mine for years now and I feel I have the potential to make that happen. And I KNOW there are so many people around me that have the same vision that I do. I would love to spend this summer making that happen.

And finally, there is my vision in Peru. Doing something more for the world than just those in my direct community is something that is a very big part of my heart. When God gave me that challenge I was completely willing to walk away from everything and go. But the way that things aren't fully working out at the moment makes me question if I'm ready to take that kind of step. It was something I was so set on and I was so passionate about it as well.

Like I said, there are so many possibilities as to what I can do with this summer before school starts up again in the fall.
I have no idea where to even start.
I'm asking for guidance, for motivation, and for God to completely rock my world.
We'll see where that takes me.
