You can learn German easily using online tutorials. The learning should be easy as the tutorials are easy and are a step by step process. It should be easy and fun to learn once you have the right and necessary resources.
maybe you should lick the bottom of your shoe turn around in a circle twice then slaps yourself 3 times then shout "dsjfiodrgfjkasjad" and you will automatically know German fluently.. i promise its the truth and nothing but the truth.
German language book, voice tapes/conversations and a friend who speaks German. Also Go to Germany with your friend and your books and live there for a year. You will be fluent when you come home. (and I bet you'd have a blast too!)
study phrases and words that are most commonly used...you could begin by learning how to order a soda or a sandwich at a restaurant....or learn to ask simple questions like, Where is the bathroom? or How do I get to the post office? then, once you become better acquainted with certain words you use over and over again, you can build up from there.
