I am learning Englsih and Bahasa Indonesia. They make me look into different world and cultures.
And I believe these 2 language would be really helpful when I go backpacking to other countries.
You have good reasons. Learn another language, gain another soul.
Just as long as you like, good for you.
I believe it is worth learn new languages in so many aspects. For me, for my study and for work and I can also learn new culture while learning language and it allows me to make more friends.
