It's hard to turn off the brain. My wife has given up on asking me if I'm done working, knowing that there is always something more on my to-do list.
What I work to avoid is getting stressed about it. I know that stress is a choice, something I create, but it still takes some concentration to get past the thoughts that lead to sleeplessness.
Part of it is planning, part is organization and part is just relaxing, knowing that I've probably committed to more than I should, and that's okay because stretching is a good way to go.
Many of us think about work outside of the office — that’s where some of our best ideas emerge. However, thinking about work often means stressing about work, which can keep us up at night or have us waking up feeling anxious, hours before the alarm clock sounds. According to a Korn Ferry study, stress caused sleep deprivation for 66% of American workers in 2018. Moreover, sleep deprivation can exacerbate our work stress, by negatively impacting cognitive functions such as judgment, critical thinking, problem solving, planning, and organization.
