Wherever I go, I take my trusty Jansport backpack as my carry-on. In this pin-covered bag, I hold plenty of things. Sometimes it’s the latest book for my book club, sometimes it’s a sweatshirt and a can of Starbucks espresso. Often times it’s just my laptop for blogging or working remotely. In addition to these sometimes items, I keep these seven essentials in there no matter where I go.
