As someone from Russia, we have even larger territory, and going by rail is almost twice as cheap as by plane. High speed rail from Saint Petersburg to Moscow will cost you ~$45, going by plane will set you back ~$75 on the cheapest flight with hand luggage only. Considering the time losses associated with airports, with rail you'll be at your destination almost as fast for way cheaper, so this option is widely preferred. Same story with long distance trips - I plan on going for a 1000km trip in July, and train ticket costed me the same $45, while cheapest plane tickets go around $100. It's also a night train with beds and all, so I have one night accommodation for free while on my way. Depart - have a nice sleep - be on your destination in the morning and have a full day to yourself, fully rested. If you're feeling adventurous, you can go all the way from Moscow to Vladivostok by single train for $250. This will take almost a week, but it will get you around half the planet for that money.

But are you happy? You can buy tingles but one thing that is not able to be store bought is oxytocin. Serotonin/dopamine/adrenaline is enshittificated. I guess Opioids are to some degree store bought oxytocin, but I like momma's food over every restaurant period. After a period of eating random shit I always crave momma's food and simple food, not Michelin. And opiods mean it is hard, but not impossible, to enjoy momma's good again after addiction. tl;dr genuine contentness and grateful happiness beat intelligence and achievements.
