The author has made the point from a financial perspective, given that she is an advisor on financial debts etc. I won’t think people from the developed countries need to worry that much about the financial ramifications of travelling the world. This piece applies mostly to the economically underprivileged countries. Even then I feel one should travel the world while keeping the financial effects in mind. You should not run into debt while trying the see the world. However, if you have the means and no commitments that is preventing you from exploring, you should definitely travel while that opportunity lasts. You will regret loosing that later on in life.
