Firstly, a very significant requirement for learning a new language is motivation. Depending on how motivated you are, you may learn the language easier, faster, or not learn it at all. You need to check your reasons for starting this journey.
How do you actually learn a new language
Sure, there's more than one way to skin a cat, but what approach would be the easiest? It depends on your current German skills as well as on how you're used to learn, and what gives you more enjoyment during the process.I suggest the following : start with a strong grammar knowledge, and then build on it. Grammar is the heart of a language. Sure, you need some vocabulary in order to actually learn grammar, but you can obtain it along the way.
Once you understand how German works, you can start building vocabulary mainly by reading, or listening to audiobooks, by exposing yourself to the language. What grammar gives you is the confidence needed to actually use the language.
Obviously, this site is a work in progress, it aims to be in a continuous development, as you can never completely saturate a topic, but you may require additional resources in different areas, such as pronunciation (mainly audiobooks and accompanying text) etc.
You will also need a dictionary with you, and I would also recommend a notebook in which to write down all the freshly learned words for a later review.
Finally, some people have been known to learn Chinese in a few months, so there's nothing stopping you from learning German that quickly. The only thing you need is your motivation.
