Prepare to immerse yourself in the new language by purchasing necessary tools to aid you with new words and phrases that you'll encounter. Basic books like dictionaries, phrase books, or instructional language books will be extremely useful when learning and traveling.
Begin to integrate the foreign language into your daily life by watching and listening to various media types in the new language, including radio and TV shows, as well as podcasts online. Foreign newspapers and magazines often have websites in the foreign language as well. By reading, listening, singing and watching shows in the new language, you'll begin to start subconsciously learning proper phrasing and pick up associations with phrases throughout the day in your downtime.
Interact with people who speak the foreign language you are trying to learn. Look for communities of people who speak the foreign language or anyone who may be interested in doing a language exchange with you. These can be formal gatherings with groups of people or individual lunches where you practice conversing over a meal.
The best way to get completely immersed in the language is by traveling to a country where the foreign language is the main form of communication. For example, if you are trying to learn Spanish, visiting Spain or Mexico would be ideal places. Having to interact on a daily basis while relying on the new language will force you to rapidly learn the foreign language. You'll find yourself picking up the foreign language extremely quickly.
