From that base, you can still do day trips and weekend trips.
This allows to alternate between excursion weekends and relaxing weekends.
I also agree with the "1-2 years" content above - I'd really like to see the seasons cycle through in any particular place I stop.
Until I started travelling with my wife (and now a child too), one main lesson I learned was "you aren't going to need it" - every time I went travelling it was lighter than the trip before!
I guess more accurately it takes a week to get settled in. Most of that time isn't about physically removing the stuff from the bags but more about where you need to put it and what stuff you might need to go rebuy and organize, in the new country.
