I think learning a foreign language is need long time:)
In the beginning, learn the alphabet and pronunciation at the same time.
It depends on what language you are learning. If your mother language is, say, English, when you want to learn Arabic, you first must take a long time to learn writing.......but if you are learning Spanish, you don't need to learn to write the alphbets......
you can watch a lot of film's hollywood, make yourself fun and enjoy first...
you can start by studying the ways of greeting and introducing yourself :)
