Globe hopping and personal finance

Maintaining a frugal lifestyle and financial discipline is difficult in the best of times so it becomes even more difficult with the kind of job I have. In the last 6 years, I have lived in 6 different countries and this constant travel has taken a toll on my finances. Though my job pays well, tracking of where the money goes and how much I spend becomes almost impossible with the variation in income, expenditure and also the various currencies involved. It is for this very reason (among others) that I have decided that long term travel is not for me and have decided to be in one place (India).

Would love to hear from you as to how you managed/or manage your finances with a job that takes you to different countries and lifestyles all the time.
