Your implied list of priorities -- travel, interesting parties, etc -- are about as interesting to me now that I'm in my early 40s with a family as an afternoon at a toddler's daycare center probably would be to you. What you're failing to appreciate is that, just as you no longer have toddler interests, I no longer have 22-year-old interests. I am as different from you as you are from that toddler.

And it works the other direction, too. My life probably sounds boring to you in the same way that a day in your life would be boring to a toddler. Now that you're 22, you aren't just a taller version of that toddler with all the same interests. You have new interests. (That will keep happening.)
