Do what you like, but the analog and digital worlds are so intertwined that you should make sure you know the basics of both before you specialize. In a macroscopic sense everything you can sense is analog so there is no total escaping it, but now it seems that digital circuits have such an extremely high utility that nearly any and every useful electrionic device has digital components as well, so people working in both realms end up having to work together and at least understand each other.
