Just as no one can define you with their judgments, neither do you have the privilege of defining others.
When you stop judging and simply become the observer, you will know... inner peace. With that sense of inner peace, you'll find yourself free of the negative energy of resentment, and you'll be able to live a life of contentment.
A bonus is that you'll find that others are much more attracted to you.
A peaceful person attracts peaceful energy.
