Find a good community! The highest quality communities I've seen will always post some sort of learning track or syllabus, particularly for newcomers. Recently, I've been utitizing /r/reddit, but my favorite subreddit of this type is /r/hiphopheads. They have one of the most well thought out wikis I've ever seen (http://www.reddit.com/r/hiphopheads/wiki/index). I've also used the University of Texas's J-School Curriculum for learning more about Journalism (http://journalism.utexas.edu/undergraduate/curriculum).
