Collate & Create
Motivation is an important factor if you want to start doing anything.
Once you've decided to learn German and want to make fast and noticeable progress, you also need to get organized: collating information as well as effective use of online resources will support and facilitate your learning process.
Another key to success in learning German is creation and creativity. Once you've collated all information and learned all the tools supporting your efficiency it's time to create. Every time you analyze a new grammatical phenomenon in order to say or write something using that new structure is an act of creation. If you want your creation to have strong foundations, I'd advise you to activate your creativity.
