Like any other- PRACTICE and DETERMINATION. you here so thats a good sign your determined :). It's been proven that the best way to learn is to actually use your knowledge as much as possible. So, always call objects by their English names instead, or put up notes on/label everything in your house. Talk with native speakers often. Listen to audio lessons. Read English books. Basically, you want to fully immerse yourself; read it, speak it, and hear it, to have many different ways to learn and practice. It gets cemented in your brain when you use it in so many ways all the time like this.
