What is the most important thing to carry with you all the time?

With the way technology has developed, I’d say a smartphone has become the most important thing to carry. Provided you have enough battery life and good signal you can basically have the world at your fingertips. All the information you need in one tiny package that fits in your pocket.

My family and I recently went on a short road trip vacation, and having access to a map that could automatically give you directions while trying to find the optimal route is life changing. We also have access to an app that lets us track each other’s positions (we were driving two separate vehicles.) Absolutely handy little devices.
