I would say: Do 3 things at the same time for at least 1 year regularly:
1. learn the basics (vocabulary + grammar)
2. talk to a native (via a language community, eg. busuu.com)
3. read books and watch movies/TV in the target language
Start watching cartoons for small children. Thats easier and you are more likely to feel you are being successful. The same with books: Check out preschool books to see if you can already understand the basics. Another advantage: You will learn the every day language which you need when you actually talk to the natives!
