There are two major factors that can positively contribute to language learning:
- Exposure
- Practice

Exposure to the language can enable you to learn passively, while living your day to day live.  
As early as you can, try listening people speaking the language. Perhaps music, perhaps audiobooks. 
Don't try to understand everything from the get go. Get used to the sounds, and recognising the differences between utterances.
As you start learning the vocabulary piece by piece, you will realize that you already have some intuitive knowledge about the grammar.
Exposure alone can help you get quite good at understanding the language, when it is spoken. It can however hardly help you to communicate yourself.
For that you need to practice. Find someone who speakes the language you are trying to learn and is trying to learn yours. Meet, and take turns in speaking the languages to get some practice in.  Best is someone with equivalent knowledge of the language, so that no one feels awkward trying to speak, when they still feel uncertain
