1. Everyday a little bit
You can`t get around it. At least ten minutes a day, otherwise it`ll take you forever.
2. REPEAT REPEAT REPEAT
As I said, do a little everyday. But do not forget to look at what you did the day before! That`s almost more important than step 1.
3. Media
Watching movies (with subtitles if you need them) and reading books in the language you`re learning is a great way to expand your vocabulary and gain a sense for the language`s grammar.
4. Visual
Work with colours and images, that way it`s easier to remember the words and their meaning.
5. Apps
There are many great apps and websites you can use. My personal favorite is Duolingo, it`s for free and really efficient. Look it up, it has a huge amount of languages to choose from.
