If you talk to a man in a language he understands, that goes to his head. If you talk to him in his own language, that goes to his heart.

Nelson Mandela

One language sets you in a corridor for life. Two languages open every door along the way.

Frank Smith

The limits of my language are the limits of my world.

Ludwig Writtgenstein

Learn everything you can, anytime you can, from anyone you can; there will always come a time when you will be grateful you did.
