Cotton- LEAVE IT. It’s bulky, it’s heavy, it’s tougher to get clean, and it NEVER dries. Much better off with synthetic, ‘dry-fit’-type clothing.
Expensive sunglasses- Sure, I get that you want to look good, but trust me, your Prada sunnies will get beat up, and you can buy some cheapo knock-offs in any market for 1/10 the price.
Suitcases- Come on, you’re BACKPACKING. Get a backpack- they’re much easier to travel with, and honestly, you’ll feel a bit awkward trying to drag your bulky rollerbag through the sand.
Fancy dress clothes- True, you’ll probably want a nicer shirt and a pair of jeans on the road, but leave all the expensive designer threads at home.
Books- Yes, you will need one to get you started, but try to avoid lugging a library along with you. There are plenty of used book stores at which you can exchange your old books for something else.Electronic readers are a good way around this problem as well, though they inherently involve chargers, cords, batteries, etc.
Shoes- Take 2 pair, 3 at the VERY most. I know its tough, but try to be efficient with your footwear- you’ll be thankful for the additional room and the lighter load once you’re on the road.
Specialty gear- scuba masks and snorkels, fins, clip-in biking shoes, helmets- anything and everything that you might need for an activity is sure to be available for hire at the places where those activities are offered.
Wads of cash- ATMs are widely available, wherever you are traveling to, so save yourself the worry of carrying tons of cash.
A closed-minded attitude- Travel is all about seeing new places, meeting new people, and experiencing new cultures. Keep an open mind and an understanding that things will inherently be different abroad than they are in your home country. You’ll enjoy the experience much more if you do...
Your inhibitions- Traveling is also an amazing opportunity to face your fears and push your boundaries beyond their normal limits. Afraid of heights? Force yourself to bungee jump. Don’t like snakes? Get your Outback Guide to let you hold one (A non-poisonous one, of course- though they’re hard to find in Australia...). Picky eater? Sample the local fare, as exotic and unappetizing as it may seem. As a wise Irishman once told me- “You’ll never know ‘til you have a go!” Words to live by...
