Travelling is the best experience in the world. It, at least temporarily, takes your mind off from all your worries and transforms your perception towards life. As Saint Augustine said, "The world is a book and those who do not travel read only a page."Travelling teaches you certain aspects of life that you cannot learn being inside four walls. Most of all, it teaches you patience and perseverance.
However, the thing which you realise the most is that you can always take away something from every place you visit and nobody has the power to take it away from you. You start appreciating little things in life but, isn't that what life is all about?
