One really important detail to mention. An advice or a personal opinion I have. Courses, books and theory are great; but practical experience is much, much better. Only when you are actually immersed in a professional environment doing things related to a particular topic will you really understand what that kind of job is really like, what practices are standard, how to use the tools, etc. In my humble opinion, go for it as soon as you have the chance! Don’t get bogged down in theory. It’s also important, but try no to be intimidated or feel underprepared. Jump into the pool. Good luck.
