Notes on travel.
Being smart with packing is key to enjoying a trip, be it 3 days, 3 weeks or 3 months long.
Limit yourself to one bag, preferably a backpack if you're going to be walking and moving around a lot. Follow the advice from either of these pages:
Why pack light? From the onebag.com page:
Here follows a very minimal packing list. In general you don't need more than this, but you should of course adjust for climate, comfort, and niche needs. So if you're going to a beach town obviously also pack swimwear, duh (or better yet, find shorts that double as swimwear). If you're a photographer bring your camera. And so on.
Toothpaste, soap and other hygiene articles can be bought at the destination or brought with you, it's up to you.
How big a backpack do I need?
For the above list, no more than 15L. But you'll likely want to pack more than what's in there. There are many packing list examples on the "onebag" links above. You shouldn't need more than 30L, in my opinion.
But how am I supposed to survive with only three sets of clothing?
Just do your laundry during your daily shower. One set of clothing to wear, one to clean and dry, and one as a buffer for a day when you might be too busy.
The dead sinple way to clean is to use a dry bag, 5-10L in size. You simply pour some shampoo or shower gel into it, then some hot/warm water until it lathers, put clothes inside, shake around, let sit for 10 minutes or more if really dirty. Empty and rinse in the shower or sink. Usually underwear and socks are easier to wash by hand directly, and then you don't need more than a 5L dry bag. Don't worry, this method does in fact clean your clothes very well.
Hang your clothes to dry overnight or during the day, using hangers or the lightweight clothesline you brought with you.
If you are lazy, have more clothes with you and are in a country where laundry service is cheap, you can have it done for you for the equivalent of 1-2 USD per kg.
Traveling alone and want to have fun and meet people? Stay in a hostel that has good reviews (and reviews that mention a "social atmosphere") and you'll be able to meet people from all over the world. But do bring ear plugs and an eye mask.
Want to connect and make friends with locals? Learn the basics of their language or at least some phrases such as "good day", "thank you", etc. It will really make people open up.
