1. A micro-fibre towel. These things are genius. They’re light, tiny, and easy to wash. If you’re trying to pack light and need to bring your own towel, then grab one of these guys. 
2. International travel adaptor. If you’re at a luxury hotel, then chances are they’ll provide you with an electrical adaptor. But for those times when you’re out at a Parisien cafe or a Vietnamese pho shop and you need to charge your computer, then you can whip out this multi-purpose electrical wonder.
3. A smart phone - Whether you’re an iPhone fan or prefer Android, you should take your smart phone with you. Pre-load the maps, turn on your GPS, and you’ll never (well, almost never) get lost. You can also download phrase books, currency converters, flight information, and keep tabs of all the important numbers.
4. Credit cards - I’m pretty sure nobody leaves home without a credit card or several but just in case, call your bank and let them know you’re the type to travel a lot. Many banks have anti-fraud features on their cards and may put your card on hold if they see it being used outside of your residing country. It’s also a good idea to bring more than 1, in case this happens to you or one card is rejected for some reason.
5. A lightweight jacket - Even if you’re heading to the hottest country in the world, bring a lightweight jacket with you. Shopping malls, airplanes, theatres, and restaurants are some of the coldest places north of Antarctica.
6. Bank cards - ATMs are almost ubiquitous. Bring a couple bank cards with you as back up and when you need instant cash.
7. Ziplock or waterproof bags - For all your carry-on liquids (under 100 mls of course) and any thing else that may leak or needs to remain dry.
8. Tampons - This one is just for the women. Tampons can be hard to find in many countries and explaining what they are through charades in a foreign country is not as fun as it sounds. 
9. Reading material - Kindle, Nook, iPad, or a traditional paperback. Reading material is a must have for any traveler. Whether you’re catching up on the latest in your industry, losing yourself in a romance novel on the beach, or passing time during a flight delay, books will always be your best friends.
