How would your life be as an IDP?

As physicians, it is so easy to want to take the easy route and complete a high-paying "lifestyle" residency, own a nice home, make a family and spend the rest of your days enjoying your lavish life in the United States. But what if, as a physician, you could provide health care to the poorest people of the poorest nations, people who will die if you are not there? I really think it would take personal job satisfaction to the next level, bring back the essence to why medicine is an inherently good field.
This past weekend, Doctors without Borders/Medecins Sans Frontiers had an exhibit in Griffith Park called "A Refugee Camp in the Heart of the City" and it really brought me back to the core reasons of why I went to medicine. As a physician, I can go to the places that no one else goes in the world to provide health care for those dying of either starvation, malaria, TB or are suffering massive war trauma (psychological and physical). Without a physician's help through MSF, these people will not live because they will not receive the basic food, water, shelter and health care that one needs to survive the harsh conditions of being a refugee. That means that, as a physician, if I could go to a MSF-served region, people would live if I was there and die if I was not there.
Can you imagine how your life would be if you were asked to take nothing but a few personal belongings, perhaps some cattle and your family and move far away for the next couple of months, maybe even years? Then after displacing yourself, can you imagine living off of only five liters of water each day? Eating only rice, beans and corn for months on ends? Where would you go? How would you make shelter? These are all questions that refugees are forced to ask themselves when they have to move from war-torn areas to refugee camps along national borders. What local physicians would want to work in these regions, especially if they are not politically safe? MSF choses to go only where there are no other organizations present, giving themselves the optimal ability to make a difference in an affected region. Unlike most of the people I meet in medicine, I swoon at this idea - the idea of being the only person who can help others. I want to badly to be useful in this world, and working with Doctors Without Borders would stretch this idea -being useful - to the limits.
I hope that perhaps one day I will qualify, or have the means, to take time off and work for MSF. I may not find "salvation" or "happiness" through it, but I will certainly help those are are at the absolute bottom of the rung when it comes to health care access. For that, my life will not be in vain.
