Whichever you choose, I strongly recommend using
Duolingo to get some backhand knowledge before you declare a language to study. I started learning Norwegian last summer to see where my language skills were at (which I would later find out is a lot less useful than I thought because most native Norwegians know English, but that's another topic) and Duolingo helped me pick up certain things fairly quickly. If you don't start 'getting' it as quickly as you would like, take on another language.
Have some fun with it.
