I like Jack's answer. It was very good. I'd only add that the best way to speed your progress in learning any language is to use it all the time and try the mental exercise, if you can, of replacing it with your native language. If you can talk to yourself in the target language, switch your phone and computer to the target language setting, and listen to news and movies in the target language that will help. You will simulate the native language environment as much as possible, if you can't be in the country where the language is native for an extended period. Also, using Italki's community tutors, if your abilities are high already, gives you the language speech practice and feedback you need. If you can afford it, I'd recommend at least three hours a week with native speakers for a few months at least. Speaking with native speakers is the most effective way to advance your progress.

Hi Efeifere Barbosa, I'm a teacher both here on iTalki and with International House. There is no easy fast-track way to improving your English. Just as with all of the other skills, writing, reading, and listening, the only way to improve is by doing it! You improve your speaking by exercising the skill and by building it into your every day life. There are, of course, many different things that you can do (build your vocabulary, your knowledge of grammar structures, etc.) but if you're not using the language on a weekly or daily basis, you won't see much of a improvement in your fluency! SPEAK. SPEAK ALOT. MAKE MISTAKES. LEARN FROM THEM. SPEAK SOME MORE!

By practicing it will make the process easy and you will feel more confident too
