"Lift yourself by your own self; do not let yourself sink. For the self alone is the friend of the self, and the self alone is its enemy."

In the middle of the day, return to this: Your most important relationship is with your own mind. You can either rescue yourself or drown yourself.
Practical application
Pause for sixty seconds. Feel your feet on the floor. Notice that this moment is, in fact, survivable.
Reflection question
