How to understand the sentence that traveling is to spend money to suffer?

When I was a student, I was a poor traveler. But Inner Mongolia can really take the train for more than 20 hours. But at that time, I didn't feel tired, and I didn't feel that "traveling is to spend money to buy guilt." At that time, I thought that I would start working after graduating from college and make a living. I thought that I would never have time to travel again, so I quickly went out to look around while I was young, but even if I was a part-time student, I couldn't make much money, so I had to travel around.

Maybe I was young and energetic at that time, and I wouldn't feel tired, painful and happy even if I took the train for more than 20 hours. Especially on the train, you may meet friends who share your interests, or make friends who travel together through the internet, so that you will not feel bitter, let alone suffering, but happy.

Maybe after more than 20 hours on the train, I will be impatient and a little unbearable, but when we arrive at our destination, it seems that all the troubles and pains before are worth it and completely forgotten. Embrace the beautiful scenery in front of me and feel what I see in front of me. This is the poem I want to read, and it is the poem I have pursued all the way, not far from Wan Li.

Friends from all over the world who have lived in eight rooms have also eaten the simplest steamed bread with mineral water, climbed the steepest Huashan Mountain, climbed Huangshan Mountain to watch the sunrise and waited for the sea of clouds. On the top of Mount Tai, they really found that the pioneers arrived before us, shouted "I'm coming" under the Yangtze River Bridge, and held their breath to feel the sand on the banks of the Yellow River. When you see the scenery you want to see, will you still feel guilty for paying for it?
