The more you travel the better you get at it. It sounds silly but with experience you learn how to pack the right way. I remember one of my first trips abroad travelling around Europe by rail fresh out of high school. I brought all these books with me and a paint set. I really had too much stuff so I've learnt to be more economical.
We have by far the most expensive health system in the world. We spend 50 percent more per person than the next most costly nation. Americans spend more on health care than housing or food.
