After having two years of your life and schedule planned on your behalf, including the exact time you should eat, wake up or sleep and what activities you need to complete daily, life after your ORD might take some getting used to.
Since you won't have an instructor or commander dictating how you spend your days, you should think about how you spend your time. You can start by defining a daily routine of job-hunting or preparing for school and spending time with family and friends.
Taking things to the next level, you can set some projects for yourself to accomplish, like getting a driving license, learning a new skill, or exploring a new country and culture.
Finding your "why" and defining a vision for yourself will go a long way in helping you make the most of your newfound, albeit short-lived, free time. Ultimately, you need to answer this question for yourself: #WhatsYourWhy? Only then will you be able to spend your post-ORD time meaningfully.
