Live out of the country for at least two weeks.
Don't travel much, just stay in one general area (except for a few day trips).
Two weeks is the maximum I've ever been in a country. Three weeks in the longest I've ever been away from home on a vacation (that was when I was 15).
I've stayed in Montezuma for two weeks, never even really did any day trips (other than errands to the next town over).
