Many people think, that the best way to learn language is to take language classes, or to write letters to your friend, or try method of Ilija Frank but from my experience, one of the best way to learn languange is to go the dance classes.
It can be flamenco, or bachata, but if teacher speaks in, spanish, for example, you will learn the language, like a dance.
Because dance is a language and when they go together,
they go togethter.

p.s.
Aslo a good thing is, at least for learning spanish, to buy fish. They have a full aquirium in the shop and the seller, if he doesn't know english, explain your,
where this fish comes from, how to cook it, how to eat it.
