For me, a place unvisited is like an unrequited love. A dull ache that- try as you might to think it away, to convince yourself that she really wasn't the right country for you- just won't leave you in peace.
You need some reason why Beethoven, Mozart and Haydn in the 18th century all flocked to Vienna. What was it about Vienna? They must have known on some level that that is where they would flourish. It's what biologists call "selective migration.
Haydn, Beethoven, Mozart, none of them were born in Vienna. They all moved there. It became a magnet, but what made it magnetized in the first place? There has to be a seed there. In the case of Vienna of about 1780, it was this deep-seated love of music.
I've spent most of my life trying to think my way to happiness, and my failure to achieve that goal only proves, in my mind, that I am not a good enough thinker. It never occurred to me that the source of my unhappiness is not flawed thinking but thinking itself.
