Not my problems

One thing that S has taught me is that I am not in control of most things I worry about. My tactic for calming myself at night now includes listing the things I cannot control.

I cannot control people at work.
I cannot control every situation at work
I cannot control S.
I cannot contol friends.
I cannot control Dominican University/St. Kate's.
I cannot control course schedules.
I cannot control the price of health care.

Reminding myself of these things helps a lot, actually. Consequently, it's not my responsibility to worry about any of them.
