I couldn't agree more with all what you've said Carlos Castillo. But in addition, I'd like to say that the more you tend to interact more with the native speakers or perhaps some few learning partners of similar interest the better you'd get fluent in it.

One thing that most of the learners does (..and including I) is that we tends to let our 'shyness' overthrown our goals. A lot of people really get to miss wonderful opportinites to speak to the most coolest person(s) on earth through the influence of shyness, also some are lack of confidence while others are just common nature. Else we set that aside the better we get to make a tremendous achievements.

sow (verb) – to plant seed
