This is Ryan. Retired singer (I think he's too young to retire from anyting, but that's just my opinion), ex-Berliner and lover of perfectly presented fresh produce. Initially planning to spend half a year on each continent, he stopped in Europe first and stayed. And built a successful career as a Business English coach. He also got married and is now living in beautiful Munich with his wife and two children. And he has a podcast for Business English (see below). There's no stopping this man! Get in touch with him on facebook (https://www.facebook.com/ryansink?fref=ts) or Twitter ( https://twitter.com/EnglishQandA) if you want to know more about resources for Business English.
Ryan recommends Business English Q & A http://www.businessenglishqanda.com/ and I think you should listen to this podcast because it's easy to understand, has interesting guests from diverse backgrounds and has a lot of advice from each of them about improving your language skills. And English is a good language
