Today you can lay down -- lie on your living room floor, sipping bourbon, and teach yourself any language that you want to with wonderful sets such as Rosetta Stone. I highly recommend the lesser known Glossika as well. You can do it any time, therefore you can do it more and better. You can give yourself your morning pleasures in various languages. I take some "Dilbert" in various languages every single morning; it can increase your skills. Couldn't have done it 20 years ago when the idea of having any language you wanted in your pocket, coming from your phone, would have sounded like science fiction to very sophisticated people.
