When you travel, you’re in the sun more than most people thanks to months of island hopping and beach time, and entire days spent outside exploring. Wear sunscreen every single day, regardless of the weather and temperature, because you really don’t want your trip of a lifetime to result in skin cancer. Plus, it prevents premature ageing! I wear sunscreen every day, even in the middle of winter.
It's great to have a guidebook, something to point you in the right direction and give you background information on the places you're visiting. The mistake first-time travellers make, however, is only doing things listed in the guidebook – only visiting the restaurants, staying in the hostels and visiting the attractions that get the guidebook's stamp of approval. There's more to the world than the bits listed in those pages.
When I was in Peru in 2010 with the intention of hiking the Machu Pichu Trail,that year there was massive floods and we were not allowed to do that hike.I had a Goretex jacket,hiking poles and boots ,and also I purchased some things along the way ,I had another 50 days left of my trip in South America and I did not want to carry all this extra stuff in my pack sack,one of the guides told me / us that we should send it home , from Lapaz Bolivia,where postage was cheap ,about $40 USD. Doing this I saved lots of space and weight,if you want to buy something some where sent it home ,mail parsel post.
Invest in Luggage: After you figure out if you will be a “carry-on only” or “check only” type of business traveler, invest in a lightweight, durable piece of luggage that has a warranty. The same goes for a laptop bag. Whether you choose a shoulder bag or backpack, make sure it has a lot of padding and distributes weight evenly. You do not want your luggage breaking in the middle of an airport.
