My first problem was I didn't know what to learn. Most languages seem interesting to me. There are just so many to choose from! Even though from a purely "what would be most useful" standpoint, Español would be on top.
My second problem? It is stupid. Just the idea of knowing more than one language blows my mind. I get some anxiety at the idea of even trying because I just sit here wondering how that works.
The CD set I am going with has no written material. So, right now I am just learning to speak and understand audibly instead of reading and writing at the same time.
I figured down the road is when I can try adding reading and writing too.
