Esperanto is the ideal "springboard" to learning other languages. I can now watch movies in french, italian, german, etc. and understand much more than I did before, even though I have never studied those languages.
The kids in our Esperanto club learned the basics last semester and they now correspond with kids around the world!
Lastly, I was able to translate a Chinese document into English thanks to my friend who put it into Esperanto first for me. We both split the fee we charged for doing it.
