expand my vocabulary in German

I’m going to start big and come up with as many words as I can about the Universe, and write some sentences using that word.

It’s been some time since I studied German and I feel there are gaps – some where I’ve forgotten what I once knew, others where I never developed them in the first place.

I would like to be fluent in German one day, so I think I need to be more directed than my meanderings in Swedish :)

I think I’m going to pick a theme and try to get as rich a vocabulary within that area as possible, before moving onto another. This will help me revise vocabulary I already know as well as learning new words.
