There are a number of things to consider. The number one difficulty to world travel for the majority of people is the language barrier. Hundreds of different languages and dialects are spoken all over the world. If you are lucky you might speak two or three languages, but during your world travels it is likely that you will encounter languages that you do not speak. Having a plan to cope with this difficulty will be necessary. A conversion dictionary for the language in question might be useful.
Another problem that world travellers have to deal with is currency. Every country you go to will most likely require the traveller to convert their currency. Several European countries have adapted to using a common currency called the Euro which helps to make travel in between these countries much easier now but for Sweden, Denmark, the UK and some others.
Every country has laws that dictate what requirements a tourist must meet in order to enter into the country. Some countries may only require a traveller to have a valid passport. Russians, for example, can travel to such countries where English is spoken as the Maldives, the Bahamas, the Seychelles, Grenada, Dominica, Israel and some others. Other countries, for example, the UK, Canada, Australia, the USA, Malta and others require a tourist visa for travellers. Research the requirements for each country you are planning to visit. Remember to update your passport and any other documentation needed. It is a good idea to take photocopies of your passport and other important documents to take with you. If you lose the originals, you can go to the nearest embassy to get a new one.
Pack for your trip at least a couple of days in advance. Even before you pack, you should create a list of items you want to bring with you. When you pack, have that list with you. It will make the packing faster and easier. It is also useful to take only necessary things and fewer bags along with you. Folding your clothes with a more efficient technique can help you.
Knowing the laws of each country that you will visit during your trip can prove to be extremely difficult. A great source of information that connects to the most relevant things a tourist should know about each country is a world travel guide either online or offline. This type of guide will let you know which side of the road you need to drive on and things of that nature. A downloaded guide works offline without an internet connection. Keeping it with you during the course of your travels may prove to be an invaluable help. You only have to pick a country or major city to download its guide. You can also use Facebook and VK if you want to know about the world’s most exciting places and cultures, read the insider’s guides and features, full of ideas, local tips and travel experiences.
During your travels it is important to pay attention to what you eat. Staying healthy while you are travelling abroad is vitally important. Before you leave for your trip call your health insurance company and see what type of coverage your plan provides for travel abroad.
I think that travelling round the world is a part of education. It is more realistic and practical than solving calculus problems. Travelling is certainly a beautiful hobby. It teaches you many things about living your life wisely. You meet different people. You learn lessons.
