Is there any Easy way to learn German?

I need (want?) to learn German to write letters for to my Swiss-german friend, but still the German language is still so so very difficult to learn.

I thought German was simillar to English because both language shared the same common lingual roots. (no need to use lingual again since you are already talking about language)

But, in fact, it is totally different. So, how can I learn German? Even learning and remembering words and useful terms is hard to me. I am in a kind of dilemma.

Learning German can be very frustrating if you spend a lot of time with the grammar. In fact, there are many foreigners (mainly Southern Europe) who never (or barely) learnt German at school and they are doing just fine.

In the beginning, try to stick to simple grammar and simple words and just have fun using it. One great thing about German is that a native speaker will always understand you even if you make a lot of mistakes. You can also ask that person to give advice how you can say things in a better way.

I am not lying, it will become very difficult the deeper you get into it. In the beginning however, just use it as much as you can and try to enjoy it.
