A phrase that stuck to me is 'No one is going to remember you for what you do, but will remember you for how you made them feel.' Anyone that's made me feel shitty, made me feel less than, unworthy, undeserving...I remember. I remember it all clearly. I offer no grace for those kind of people. I'll engulf them with light. One where it's so blindingly bright, they dissappear. No horid person deserves room in my mind.
