Okay, so I've seen many people who travel and that's okay, I mean, who doesn't love travelling and exploring different cities, cultures, and more? But I know many people who have travelled without having read about the country they are travelling to.
Why do we have to read before travelling to a country?
1. Knowing exactly where the country is gives you a clearer idea of its geography. For example, I met this guy who went to England, and he said «I'm going to the UK!», I asked «Oh! Where exactly? Would you go to Scotland» And he said «What do you mean? And no, why would I go there? I said the UK, not Scotland, duh»... Mm, OK.
2. If you read about its geography, it'll be easier for you to decide the places you'd go within the country. You will know what the safest places are!
3. You do have to read about its history. Please. There's nothing more beautiful than being in a different country knowing what happened right where you are and why, when! It makes you feel like you're part of them! Learning about culture is excessively beautiful!!!
4. You can read about tourism and the places, you must visit, such as museums, events, restaurants, cities, streets, avenues, shops! Everything! I mean, going to London and forget about the London Eye? No way! Or going to Mexico and forget about tacos, tequila and folk dance of Mexico?! Whaaaat?! ¡No manches!
5. Try to learn their language, at least a few words! Learning is beautiful. And when you learn a language you learn a lot about different cultures.
6. Read about the do's and don'ts! This is very important, who knows? Perhaps you can avoid some years in jail.
I have lots of reasons why you should read about your next favourite place but seriously, do you want natives to think you're ignorant/idiot just because you don't know (enough) about their culture, cuisine, history or geography? Do you really want to travel without knowing where you are and what happened there?
Read. It's good, it's healthy and it's fun.
