I couldn't help but steer my readers to a post written by my Spanish tutor, Siskia Lagomarsino. She talks about the process of learning one of the native languages of Mexico, Nahuatl, something I have a great interest in picking up in the future myself.
Do yourself a favor and check out her post on Fluent in 3 Months, then check out her own blog, The Polyglotist, for more language learning stories. She's a great tutor, so if you're interested in learning Spanish or Japanese, I'd highly recommend her.
