I speak 4 languages so far and I can say it definitely broadens the way you think, the way you analyze things, even the way you learn.

Moreover, learning languages decreases the probabilities of developing Alzheimer. This is because you are constantly creating new neurons and synapses in your brain.

The best of it is to be able to communicate with other people! As a plus, there are expressions or words that you can't possibly translate into other languages, which well, it can be a disadvantage in certain contexts I guess 😁
