It's not easy to start again what you have leave by years.
I was very fluently in English when I was a marketing manager in an exporter furniture. (2001) My boss came from England, so I can laugh and get discussion in English every day.

After I resign and build my own office as architecture consultant, I never practice English.  It has been a long time ago. And now I must practice again because I will meet my design client, a Spain man next week. And I  should prepare to go to Ubud this October, because I get free ticket fromUWRF. Can you imagine it? There will be so many International writers there. So I should refine and fix my English again, from now on :D

And of course I have to read, write and make conversation in English well because I have aims to walking around the world. Aamiin
