When learning a language is important to memorize and retain all the information you can. When I first started to learn Japanese this was a need I felt. So I got a notebook and started to write down every word and expression that I came across so I wouldn’t forget, this has been a major learning aid for me because you can’t learn a language without learning vocabulary can you?
I get my vocabulary from every source that I can, Japanese music, tv shows, anime, etc.
I took some pictures of my notebook with my cell-phone’s camera (hence the bad quality…)
