People are different. And so require different things.
Also, people change over time, and therefore what they "require" or can accommodate changes over time too.
Some artists/writers need the bustle of crowd noise and the presence of lots of people to be creative. For them crowds are like the well that they dip their creative bucket into. Or for some the sounds of crowds is like a white noise machine that helps them focus their thoughts.
Others need space and quiet in order to help them nurture and tap into that small, fragile creative voice that, for them, can easily get lost in the mayhem of too many people in too close proximity around them without any respite. Some people are sensitive to noise or the presence of other humans to such a degree that they feel like other people are "living all over" them.
There are both personal and cultural factors that determine how comfortable a person is with varying levels of social contact.
If you grow up in a highly populated area with very little "open space" then your expectations are set by your experience and
by cultural expectations. The below diagram would look quite different for someone who grew up in India or China versus some
one who grew up living at the North Pole or in the Australian outback or Greenland.
When I was twelve I lived for a year on the outskirts of a city with a population of 30 million people.
As an adult I lived in a city with a population of nearly 741,000 and moved to a city with a population of 8 million people.
While that "city never slept" and there were always cool things happening, most of those things took money and "getting
away from it all" required money and on top of that I seldom wanted to expose myself to such things because I felt like
doing so squashed down and drowned out my own creative pursuits and aspirations—I felt contaminated by other people's shit.
This was an icky feeling for me.
So then I moved to a city with a population of 3 million that was much more affordable, had more trees and open spaces
but also had far less going on and "getting away from it all" was still too expensive and everybody else tried to "get away"
at the same time and used the same ring of freeway systems so that the whole thing felt gross, unhealthy and besides that,
the city felt a bit provincial with pockets of cool things/neighborhoods and way too busy and not nearly busy enough all at
the same time.
So I moved again.
I tried making a go of it in a city not too far from where I grew up that had (at the time) a population of roughly 396,000
but the place and I had changed. It had become exorbitantly expensive, the air was as polluted as I remember the air in
LA being in the 1980s and "getting away from it all" was an expensive luxury reserved mostly for the wealthy. The level of
sacrifice I'd have to make with my time and the amount of debt I'd have to shoulder just to afford to live there felt like
a devil's bargain that I couldn't live with so I moved again.
I currently live in a rural area with a population of about 4,600. Locally, the greater area around where I live has a
full-time population of just over 25,000 that (during the summer months) has to accommodate about a quarter of a million tourists.
The tourists are quickly destroying what made this place what it was. But I live in a small pocket within the greater area
and so the impact (while regrettable) isn't as bad right around me as it is in the region.
I've been far more productive creatively where I live now than I've been anywhere else I've lived. It isn't perfect, but the world
today is far from perfect and much of it makes absolutely no sense.
