No matter how serious the challenge is, from ego-driven to life-threatening, there is one theme that everyone who feels stress shares: feeling out of control. Those who are unemployed feel helpless to be in that position, and many with jobs are unhappy as they feel like their priorities and time are dictated by others.
One antidote is to control whatever you can. One reason that the military emphasizes perfectly making the bed upon waking up is that we can start each day immediately accomplishing something small and within our control.
If your stress stems from feeling out of control of your life, take it back by taking control of the small wins.
