Find some way of going to an Asian country (I recommend China or Vietnam, others might suggest Thailand) once a year for whatever reason you can (mates holiday - if your missus is alright with that - some are as it entitles them to a holiday 'with the girls') or preferably 'on business' (I don't know what you do but I am sure there is a conference or trade fair in Shanghai or Guangzhou or somewhere that you might have cause to visit). If you prefer the old 'Turkish delight' then you can always head to Africa or the Caribbean, I expect.
Secretly brush up on the language, so you can be a skilled negotiator when you get there.
Find out the market prices in the place you're planning on mongering in.
Stuff a load of (by British standards) small change into your pocket and go mental for a week. Don't forget to bag up - you don't want to be coming home with the clap.
Return to your happy home for 51 weeks.
Repeat ad infinitum.
