I love a good Tabris troll thread.
Anyway, I'm also in my early 30s and by this age, most of us from metropolitan areas have done that Vegas party life plenty by this point. It's fun and exciting, but not every type of joy is bombastic, and bombastic joys aren't always the deepest or longest lasting.
You're in sales, which means you have a particular personality type that most people don't have. You're probably an extreme extrovert, which means you get energy from other people. You probably also have a naturally low adrenaline level, which means you have to seek it out in activities. You also definitely have a love of brand and appearance, which isn't going to be satisfied with personal, familial activities.
Other people are different, or they move into different phases. As we get older, most of us enjoy the big night out less and less, or at least less frequently. I used to want to go big every weekend, now I'd much rather smoke a brisket 9 out of 10 opportunities.
