I'm not @darkwater but I will use this question to try to put my thoughts together a bit.
So, on my first week it was hard. I was working in very central London and I had access to peak consumers options. I like it, I was used to have anything that crossed my mind being readily accessible for me. Except for shorts that week, apparently. My order from Amazon did not arrive and I was trusting Amazon enough to skip going to a high street shop to buy one up until the last day.
So I flew to Cuba with no short pants. Turns out its very hard to buy clothes in Cuba, I didn't know how locals manage to do it and I was out of luck. If you stay at a resort, there are shops in the hotel but I wasn't going to stay in a resort. I found out that there's a shopping mall in Havana and you can even use your credit card to do purchases(I went there with very little cash as my research indicated that ATMs work fine. In reality, not that fine). The mall was nothing like the ones I was used to and the shops sell knock offs at original prices.
Anyway, I was for a rough start so I was forced to improvise and not follow my initial plan. Later the things stabilised, I was able to find an ATM that will let me withdraw cash from my HSBC account but by the time I already befriended a few local people who would give me a glimpse into the actual daily life in Cuba. I went to the places I was planing to go, great beaches and everything but my mind got occupied with the way everything works in Cuba, so I kept paying attention.
First week, I was missing my routine in London. The snacks, the entertainment, even the food. I was feeling like missing out and I had no idea how to enjoy life without those things.
Then I realised that I was feeling bad because I was expecting to spend my time the way I spend it in London but I was not in London. The consumerist lifestyle in London has defined my expectation and I was annoyed because those expectations are not met by Cuba. A nice restaurant would take the edge of it but the core problem persisted.
Then I started looking inside. Do I really need to spend money for enjoyment? Do I really need to taste a different beer every time and judge it? Does my pizza needs to be proper Italian? Do I need advertisements to give me ideas to do or buy something? I found out that no, I don't need ads and I don't need to occupy my mind with the decision making of the kind if lager I should drink tonight. Instead of riding the amusement park of consumerism, I can simply be curios and explore!
My second week was much more chill. I knew which beer I like, I like Cristal and I have no interest in Bucanero or Presidente. Big deal, it's a nice beer and available pretty much everywhere. Maybe Heineken is better but I don't care anymore, that's not something that I would spend time on.
I need something sugary? Well, it's not available on every corner so I will just not have it now and If I still want it I will buy one of the few snacks that are available. It is alright not to have it now.
I found myself to consume much less and be quite content with it and I found out that I was enjoying the stuff I consumed much more. My actions were no longer guided by the consumer infrastructure and the simplest things were giving me more joy than the speciality stuff that I had to buy to out do the regular things I buy. A fish at a local restourant tastes much better when I'm hungry than the fish I would eat at the restaurant that is highly rated and endorsed by influencers.
Don't get me wrong, I do value and enjoy the variety of food, items and entertainment in the western societies however I no longer believe that these things are the main ingredients for a happy life or society. It's nice to have those things, it brings so much culture too but if you think that your life will be less fulfilling without those you will be wrong. These are nice to have but there is a danger to give up on actually fulfilling stuff in order to live a consumerist life. Let's not try to optimize for having ever more food and gadgets and things.
