Stay away from Youtube tutorials if possible. Even if the videos themselves are good, Youtube is designed to keep you on their site consuming content rather than actually coding yourself.
And don't just read tutorials either, try to pick some project that you want to create (for example a website) and work on that while going along with whatever tutorial you chose. You won't really learn otherwise.
