Traveling is a rewarding experience, but if you do not speak the language of the country or English it may be difficult.
If you have decided to go on a trip, it is to meet people and discover their culture, so this is a first reason to learn a foreign language.

Nowadays, English has become almost mandatory in some areas.
Some jobs are better paid when you speak a foreign language.
Three languages ​​are particularly appreciated by recruiters, namely English, Spanish and german.

To keep a brain in good shape:

As surprising as it may seem, learning a new language can be a real sport for meninges.

Knowledge of a second language would help to develop verbal intelligence, conceptual training, global reasoning and to stimulate the discovery of rules that underlie the solution of problems.
It is also a great way to fight against brain degeneration and especially Alzheimer's disease.

Knowing a new language is really satisfying in everyday life: helping a tourist, meeting and talking with a traveler on the train, being able to tell a "secret" to a friend who speaks the same language without worrying about the rest of the group, doing research on internet in the language learned, etc.
These are small pleasures, I grant you, but what happiness! Not to mention that you will be proud of yourself!
