Man, TED talks suck.
That guy scammed you into learning a conlang with the excuse that it does something that all languages do and nobody is even telling you.
Just learn a romance language if you want access to a family of concepts that will carry over easily, friend. It comes with the bonus of being able to talk to people.
Anyway, I'm often light on personal info here, but I'm in a bilingual territory, learned English as a kid, the basics of a couple others through life stuff and I get a few more through osmosis because all languages do that Esperanto trick.
