You can speak any thing you want!
Watch a lot of dramas related to that language!!
Another way to a perfect start off Is to learn alphabets
However good all the above may sound, I think the best way to learn a language is to have a motive. When I first started to learn Japanese I wanted to travel to Japan by the end of the year, so I wanted to at least be able to read the signs and understand instructions. Later on I found out that the travel won't be possible, so I practiced less, but kept it going. After a while it was a habit and it's important that it takes very little time in the specific app that I am using. So it was easy to keep up even without my initial motivation. I found out other motives later on, like not to break my strike, like I maybe I'll travel later so I should keep learning, like the excitement that I got when I started to understand the symbols e.t.c.
To sum up, start small then build up. How are you going to start ? Find a motive to do it ! Something fun like a travel, or simply look at the learning process with curiosity. "What new I am going to learn ? ", "I can understand this much by now ", maybe have a look at the culture of the natives. It is important to find out why you do this and then you'll see what moves you to keep up. Then it's just practice practice practice, first in writing or listening because it seems easier to me, then speaking.
Then, invest in a tutor/lesson. Just 30 mins a week can feel like a huge confidence boost.
Finally, an app. One that has daily challenges so there are incentives to using it every day, even if only for a few minutes.
Listening to or watching programmes of that language will help to tune in to the sounds and phrases.
Use some apps (I really like Duolinguo) to make it fun.
When you feel confident with the sounds of the lenguage (it can be tricky if it's very different from the ones you already speak) try watching cartoons and TV series with subtitles in the target language.
You can start with cartoons you already seen in your native language and then move to something new.
If you have some friends who are already fluent try some easy conversations to practice your speaking skills too.
This is a solid start.
You cannot skip the grammar which I think is best explained in grammar books. I just think that starting in a fun way will give you the motivation to do also the "boring" part 🙂
