You cannot. It takes effort. Anyway, I dont want to be the guy with the criticism again, but you also, only spend six words to generate a question here, and that is already too little effort to begin with, (in my humble opinion).

You can't....as with all things, it takes time and effort. However, as others have pointed out, you can certainly improve by watching films, listening to podcasts and internet audio programmes and by reading newspapers and articles online. And of course, by speaking to natives...

Good luck with it!

It's all about exposure. You should listen to native english speakers frequently to get the hang of the sounds.
yeah.. I don't know. It's never going to be a quick thing but that doesn't mean it can't be fun.

buy sticky notes and write the names of furniture in your house in english on them so when you see them you can read the english word?

It really depends on how you normally like to learn things.
