Stress
There are two kinds of stress when it comes to working in international sales.
The first kind: Anyone who's ever worked in sales will tell you that balancing the needs of the client while also making a profit and representing your company to the best of your abilities is hard work. The "international" part of international sales adds another, often complex layer to the equation: Not only do you need to think about how your company's product will sell and function overseas (if it even will), but you have to understand where people are coming from and how business is conducted in other cultures.
The second kind of stress pertains to the travel component of this job. Not only does planning a trip abroad require a lot of thought, effort, and time, but you have to be prepared for everything to go pear-shaped. Sitting in a foreign airport, knowing you're going to miss your meeting the next morning because your plane has yet to appear, is enough to make anyone's blood pressure rise. Furthermore, trying to juggle your regular workload while traveling and working overseas can be exhausting.
