Hmm, brains, heart, courage and... oh, wait, that's the Yellow Brick Road.

But seriously, have you ever done any backpacking before? Do you have a clue as to what you are doing? That's the first thing on your list-awareness of where you are going and what to do once you get there with the stuff you have brought.

There are many gear lists posted here by various members, but none of those lists may be suitable for you or where you are going. Figuring that out requires more info than what you have supplied. If you are going in winter, I have a winter gear list posted in the winter forum.
