Taking a job abroad is all about the experience you get and the benefits you gain. It will change your life, to put it simply.
You may gain exposure to cultures you have not experienced before or have the chance to serve others less privileged than you.
Most develop maturity, learn self-reliance and improve their money management. Enhanced social skills and teamworking ability inevitably come from meeting new people.
When you're on the job, it's usually the obvious stuff you forget when you're away, so remember...
- don't accept things off those you don't know
- use your instincts, if something is dodgy, run!
- don't get money out in front of strangers
- don't carry anything for anyone you don't know
- make sure you know about the fire exits in any hostels you're in
- travel in numbers if possible
