I think as a teenager and young child, I had a sense of wonder or something about the world, and if i played Nintendo Game boy for 7 hours straight and ate 5 donuts it was a good day. What you are describing I think is just life. Whatever thrill you seek and get from anything is very brief and fleeting, and then you are basically starting from scratch and looking for the next journey to the next thing.
It is like sex, it is kinda a big deal but they say the average time is like 10 minutes, i mean i could spend 5 hours on a dating site in one night you know. The thrill wears off quickly. If you climb mount everest, getting to the peak is just a brief time of a few minutes where you look down at everything, then you go back down, you risk your life getting up it and down it. Then you plan for the next year to climb mount kilimanjaro, for a quick thrill then the next thing. Drugs or alcohol is very similar, you get a quick buzz and then crash. Or extreme sports, like skydiving, you are only in the air for like 2 minutes, but you had to fly to this location and then get in a helicopter to fall out for that brief time. I was in helicopter tours in NY and Philadelphia and you feel great for that short 15 or 20 minute ride which costs like $200. And i was in a speedboat a few months ago that went 78mph, you had to drive 2 hours to get to the speedboat, it was a 2 hour tour for $200 and of the 2 hours, you are only going full speed for 10-15 minutes (twice for 6 or 7 minutes each time). Nothing lasts forever and everything in life is a quick thrill and then back to your same BS routine
