>>The only thing I find Intimidating is that I only speak english. Wouldn't be a problem is some places like the UK where it's the native language - but I wonder how difficult is would be in Asia.
No probs at all in Hong Kong or Singapore or Bangkok or Kuala Lumpur or Seoul or Taipei. More difficulties outside big cities in China or anywhere else.
A lot of educated people are proud to speak English wherever you go. In Europe where multilingual is the norm, often they'll identify you as North American and will initiate conversation in English.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
