Three days ago I packed my bag for the very first time, and I realized, whoa I'm going to have to do laundry like every 4 days. Don't get me wrong the pack can hold a ton, but because I want the pack to be as light as possible while still having enough stuff for me to live with for the next 10 months. The key thing about packing I think is not thinking about how nice it would be to have something but if you are only going to use a thing for one purpose don't bring it. You don't have the room to take a bunch of clothing items with you that you will only use as one thing. For example, I have a swimsuit that look like nice dress shorts,this won't work for girls of course, but for guys, they are great. You need things that have more than one purpose.
