I hope this helps! Good luck:)

1) Research

You will research all over the internet looking for books, articles, lessons, websites and other language materials.This usually happens after you have heard someone speak that language or simply because you have always wanted to learn that language but never made a move.

2) Start

You will start learning from online websites and probably read grammar books. A lot of information at once and the language just seems so complicated and strage.This leads us to our next step.

3) boredom 

You start getting bored and then lack of motivation occurs. This is bad, you start to look for excuses and running away from the language instead of facing it.

4) Motivation

After you figure out that you are unstoppable, you are completely motivated and have figured out that you love that language and whatever it takes you will go through the tough times because you are sure that on the other side of the road you will be able to speak that language. You get too excited and from here you go to the next step...

5) "HARD WORK"

You sit down and actualy do the hard work which is usually taking a lot of notes,watching a lot of videos, taking a lot of lessons. During this time your at your highest level of motivation and this is the best time to learn that language.

6)Difficulty 

You will notice that you have spent so much time studying the language and your not seeing any huge improvement anymore. The grammar is too complicated and you feel its time to start to practice speaking with someone.

7) Surprised

During your practice with someone, you suddenly feel that you are able to speak that language.It does not happen at a specific time. I call this a surprise because you yourself did not know that you spoke that language. It just all happened naturally after long hours of hard work and practice.

8) Speaking

Your surprised by how much you love that language you start watching movies with that language, speaking to people from that country and you feel that the language and culture became part of you. Everytime you hear someone speak that language you get too excited either because you understand what they are saying or because you are too social and want to surprise them with your ability to speak. Congratulations you "SPEAK" that language!

If you are a beginner I would recommend not worrying about time, you should realize that learning a language is like a baby learning how to walk, at first you wont be able to stand then with time and practive you will be able to stand and move a couple of steps then fall. Relating this to languages I would say that at first you will find it very difficult, relaxxx its not. Its just something new, and for us human beings everything that is new scares us. Now after taking some lessons and doing some practice on speaking and hearing you start to feel that the language is not as difficult as you thought it was... now at this point your a standing baby. After you stood up, its time to learn to walk and this is the part when you can learn the language in exactly 6 months. 6 months but constantly every day dedicating 30 minutes of your time just reading or learning new words and I promise you that you will be able to speak. After that you will aquire a skill and be able to communicate about any topic with barely any gramatical mistakes. The only difficult time is the beginning, trust me as soon as you stand up everything else is just fun and amazing... good luck and if you need any help or advice let me know!
