EDC is as much about contemplation as it is about carrying stuff.
It's about observation, choices, and refinement.
One can get lost trying to stuff their pockets based on the banter of internet kibitzers and armchair commandos. But, ultimately, EDC is about discovering what you need to carry, not what someone else thinks you should carry.
Certainly, there are arguments to be made regarding the utility and practicality of certain things (a gentleman should always carry a knife) but, ultimately, EDC is a discipline comprised of personal choice and individual need.
After all, they're your pockets.
