How can you prepare yourself to get into the brutal and rugged state of mind required for Skyrim?
My recommendation:
Read Beowolf
Watch Conan (with Arnold Shwarzenegger, not that new crap)
Listen to music like this:

Read awesome bits of Norse mythology like this:

What do suggest doing to get yourself into that Brutal sense of spirit?
