One of the biggest changes I've noticed the past 5 years, is my planning timeframe. Instead of embarking on spontaneous trips and shenanigans, I find myself booking weekend and international trips several months in advance. It's not necessarily a bad thing, just a little age showing through the cracks because everyone else in my peer group needs to plan ahead.

My dinosaur is bigger than yours.

Hell, before you know it, you won't even have time to plan for anything anymore.
