As a consequence of growing up in a diverse and multicultural society like India, I am fluent in 4 languages (English, Hindi, Marathi and Konkani). I am currently learning French from Duolingo and Kannada from a language book that I purchased sometime back. Coming to your question, there seems to be no right way to learn a language except for selecting a learning resource and diving straight into it. Some languages are easy and some are quite hard but the trick seems to be in getting familiar with the initial phrases and then learning the grammatical rules. Grammatical and syntactical rules are like the glue that hold the words in place and I would advise you to focus on them. Talking to people who speak the language (can be quite awkward for the beginner) and reading passages aloud will end up helping you as well. There is no timeline to this and getting fluent in a language is a function of your efforts and the difficulty of the language you have chosen. If the language that you want to learn is on Duolingo, that's the best place to start.
