Maybe the reason travelers over pack is because they don’t have enough experience to know what’s really important.
I’m sure a few seasoned travelers still tend to take too much, but for the most part, the veterans take as little as possible. They know what they’ll need and what they won’t need. They know the experience well, so there’s less room for “just in case.”
I feel about the same for living.
Maybe the reason we over spend, over prep, over eat, over whatever is because we don’t have enough experience to know what’s really important.
