Best ways to learn languages better

Most of the people are stuck in one country using only one language from their birth. But the world is much bigger than only one country and there is a lot of languages out there. In order to being able to talk with people from other countries, you have to learn another language. And learning a language is kind of hard if you're not actually using it somehow. I will tell you how I was and still am learning english. And I hope it will be helpful to everyone else who is learning any other language.
