Contact forum member "OneaDay" and talk to him. He has some serious game relevant to your culture. Most of the info here ISN'T going to apply to you since you are from and live in Brazil.
That's a whole different ballgame, culture, and way of approaching women there. You have to be "all in" or you are going to get nothing. You're not competing with video game dorks who sit around on Tinder all day wondering what to text next. I probably have about 1 year worth of time spent in Brasil and even that, I don't feel, qualifies me to answer your question or give you advice.
So, to sum it up, talk to a Brazilian who understands your culture instead of just listening to anyone, because your culture is going to require you to be more direct and go after what you want than someone in the USA/UK.
