Learning to forgive those who've harmed you or others is a way of relieving yourself of the burden of anger.
Have you ever heard the saying, "When you forgive someone, it's for YOU not for them?"
There's truth to it because I held anger toward someone for many years who had done wrong by me.
When I finally "let it go" and forgave that person (without even telling them), a sense of relief came over me.
I was able to think clearer and focus more on my mission and purpose in life.
I can even say that after I quit drinking, became sober and started to turn my life around, there was a time I was very angry at myself.
Angry that the younger version of me ever even started drinking in the first place. Not to mention all the pain I caused myself for so many years.
But I forgave myself too!
Mahatma Gandhi once said, "The weak can never forgive. Forgiveness is an attribute of the strong."
If someone's harmed you (including yourself), maybe not right away, but at some time in time, make a plan to forgive them.
You're sense of well being and happiness will thank you.
