The quickest way to learn a new language efficiently is to immerse yourself in a culture where your target language is used. Think about how a baby learns her first language; she learns by absorbing information directly from native speakers and imitating them. As soon as you start learning a new language, it is very important to also include cultural sources as your channels to learn. I have a habit of picking a movie/TV series I enjoy and watching some of the dialogue-heavy scenes repeatedly. I watch them with English subtitles for the first few times, and later I watch them without subtitles as I become familiar with the dialogues. Finally, I try to read the dialogues out loud. This has been a great way to practice my listening and speaking skills. The great thing about it is that you can keep yourself motivated easily if you pick shows you enjoy. Also, communicating with native speakers directly is the another great way to put your language skill into practice. You can look for communities of people who speak your target language in your city, attend social events that let you meet native speakers. If you prefer practicing a language with native speakers online, there are also many options of language learning apps that match people up based on their language preferences. Apps such as HelloTalk and Tandem are quite popular.
