"None are so empty as those who are full of themselves." - Benjamin Whichcote I couldn't agree more. I seem to have found that it's more so the narcissistic people whom seem to be the most full of themselves.
Stay strong and remain kind. I allowed anger and resentments of the arrogant to take my kindness from me. I'm just now learning to regain that inside me, which makes me a much better version of the real me! Never allow anyone to dull your shine!
