Anger, a core emotion, is a signal that one or more of your personal boundaries have been invaded (e.g., mental, physical, emotional, sexual, financial, spiritual, social). It provides energy to create, implement, reassess/reset appropriate personal limits. Without anger you may lack the motivation and energy to take appropriate corrective action or you may become complacent and begin to tolerate the intolerable. Unmanaged anger can lead to bitterness, illness, injury, and even death.

Bitterness, hostility, and unforgiveness are hungry parasites that leave little if anything for the brain or heart to eat.

For every day you allow yourself to remain in a state of anger, you have given up a day of health that can impact the rest of your life.
