Perhaps invest in Rosetta Stone.

But the easiest way is to surround yourself with English speaking people. That is how my friend Jens learned better English.

It’s common to have heard that watching television had helped them learn to understand and speak better English.

Spoken English isn’t necessarily proper usage.

It is a start however.

I would practice reading newspapers and magazines of interest.

Obtain a dual language dictionary; English and your native language.

Learn the lyrics to songs that you enjoy. Find them on the Web.

You seem to be able to be able to post your question, so you may be well on your way.

Good Luck
