It's really no secret that I have an interest in Everyday Carry.
While "everyday carry" is not survival preparations, it borders somewhere between life hacking and a life style. I have found great value in having the most essential things I want throughout the day with me when they're needed.
It's the things like nail clippers, for when my nails start clackety clacking the keyboard if they start getting a bit too long, or a AA battery for my wireless mouse when it's old battery finally starts dying unexpectedly.
Having a few items that can get you through the day, while making your life better and easier really makes a difference in how you feel when you leave work.
