It's Embarkation Day... Now What?

So you are about to leave on your trip that you've been stressing about for a while. What do you need to get done the day of?

1) Make sure your homebase has all of the necessary paperwork he/she needs. Also double check your own paperwork. Make sure you have all of your set flights, accommodations, and adventures printed. It's a lot easier to find a hostel when you have the address!
2) Double check your packing list. And maybe take out a couple more things. Chances are you
over-packed.
3) Check in for your flights. Make sure you have your flight info for your return leg printed and saved.
4) Withdraw cash (if you haven't done so already).
5) Dress comfortably. No tight clothes. You'll be miserable!
6) Wear shoes you can easily take off. You will be going through many rounds of customs. And you will probably want to be barefoot on at least part of your 10+ hour flight.
7) Delete all of your unnecessary applications and photos/videos on your phone. You need all of the memory you can get!
8) Pack a snack. Just do it.
9) Mentally prepare. It is going to be sometimes awesome and other times terrifying! But that's exactly why you are going!
10) Shower right before you leave. You will be wishing you had if you don't.
11) Pack your chargers. It's always the last thing that people pack and usually what they forget.
