1) Daily contact with the language: allow yourself at least 15 minutes a day to practise your English
2) Choose what you like the most, for example listening to music or to podcasts, watching series or movies, reading fiction or articles on the Internet and do “that” in English
3) Use all the input from the activities you enjoy to write your journal or an essay or an article or just a note and share it with your teacher
4) Set a real goal: sitting for an exam, learning the culture, socialising, and go for it
5) Travel to a country where the language is spoken to check how worthy all your efforts have been and, of course, to keep improving “in situ”
