When I was a kid, I wanted to park as absolutely close to the store or building as physically possible. If we parked in a spot and there was one spot even slightly closer, it was an affront if we didn't take it.
Now as an adult I find myself parking wherever I think is easy to get in and (better) get out of, and I don't mind hiking a half mile in. My definition of convenience has changed from walking to parking the car.
I'm sure this has happened in other facets of my life, but so far this is the first that I'm aware of.
