Travelling is about learning something out of the books. Do you know if you travel alone, you could actually learn a lot? I know, there are a lot of things we should take care of.
Instead of people taking care of you, you need to take care of yourself! Documents, passports, hotel check-ins and more! but imagine, for once, travelling alone..
You will definitely learn more about your self and what you can do. You can actually learn the place more than you are travelling with flocks! you see,
1) you'll be taking more interest in something it's not related to the place you're visiting!
2) you have no space of speaking the native language to find new foreigner friends!
3) MOST IMPORTANTLY, you can do exactly what you want to do, all the time!
TRY IT. whatever it is, safety does comes first, okay! :)
