Someone else commented below about the hedonic treadmill.
Travel is what creates unique experiences in people because traveling is a rare thing for people in general.
When I toured we had 220-230 shows a year, everyday in a different place. I did it for 5 years. It's hard now to even tell one year from the other.
I surely made great stories, but most of them are foggy nowadays.
Most unique experiences I have left of that time are either global events, I shared the merchandise stand with Nick Alexander the merch manager of EODM the night before he was brutally killed in the Bataclan attack, or too important to forget, like one of the crew members having a baby and rushing him to the airport so he could be there on time.
Touring is like traveling, it is in fact traveling at its best, it's like an adventure.
The only difference with traveling for leisure is that you don't stay in the same location for long, but you are away from home for a long time nonetheless.
Usually you travel around 200kms a day on average, someday it's 800km under the snow, some day it's 50kms on the coastline of beautiful Sardinia, but you might cross region borders or country borders, people speak different languages, you travel from north to south or west to east and everything changes.
East Germany and West Germany are different, German Switzerland and French Switzerland are different, Wallonia, Flanders and Brussels-area in Belgium are different.
North and South Italy are completely different.
To explain my point better I'll tell you what a musician told me.
One year we met with Bob Log III (https://en.wikipedia.org/wiki/Bob_Log_III) a few times, because we were playing in the same venues, so we spent few nights together before and after the shows.
He told us he used to make a crazy number of shows in Europe, sth like 80 shows in 3 months.
He always travels alone, at least he did at the time, and drive his own car.
One night he was going from Innsbruck in Austria to Stockholm in Sweden where he had a show 48 hours later, stopping at the northern German border to get some sleep.
He told us it wasn't uncommon for him, he did it to pack as much shows as possible in as little time as possible, earn as much money possible, and then spend a couple of holiday weeks with his family in some European city, before going back home.
But then he said he stopped doing it.
He was only doing 30 shows in a row at max, no more than that.
Why, we asked.
He said: because as fun as it is to be always around partying with the great people that come at my shows who am I grateful to, because they are the ones allowing me to live my life as a musician, I started forgetting things.
I couldn't remember faces, dates, venues.
I kept going to the same places and not remembering people names.
So he decided to do less shows, max 30, in a bit less than two months, to make good memories that stayed.
What I wanna say is that it is absolutely non-boring, non-repetitive and definitely not something that feel like working, not at the level I did it anyway, but too much is too much, even too much fun can be too much and lose its meaning.
