Great piece of advice:

Next time your day gets crazy...and you feel the stress coming out of your mouth and ears, remind yourself of this:

ALL STRESS COMES FROM RESISTING WHAT IS. (-Oprah)

Don't let your wheels spin too long on something that you can't change.

Plus, stress ruins the sleep you do get.  When you stress, your body releases cortisol. Cortisol messes with serotonin, which helps you sleep.  You'll get sleep... but a less restful sleep.  No bueno!
