But leaving one's comfort zone is psychological; I think one can do it perhaps better at home -for it is how we are, with all our 'trappings' (It is easy to be somewhat different for a couple of days elsewhere, but then back come our habits!)

I think if we really want/need to leave it, we will!

But most really don't want to, I reckon!

We are told (by some spiritual teachers/writers. e,g Castaneda's Don Juan,) that we have a perceptual bubble that clicks-shut at about age 2; and most stay in it all their life.

I think this is true.

But it is possible to break though this duly, if we want... -And then life becomes a lot freer, and we learn so much!!
