Travelling is the best way to obtain experience from it. As a result, you can interact with others smoothly and learning from them a lot.
In addition, you can learn about time managment, as you can know the value of time. Morever, you will learn how to be self independence, so you can depend on yourself by doing everthing thing alone.
Although, travelling abroad is a good way to learn new things, but we believe, that we will have to pay a cost at the same time.
