Recently I stumbled across this one:
"Words are in my not-so-humble opinion our most inexhaustible source of magic, capable of both inflicting injury and remedying it." Albus Dumbledore
Heartened by it because new words lead to new meanings, new neural pathways and rewiring those negative beliefs that were instilled in me as a child.
Thought I might add it as part of my signature

I don't know if there's already a similar thread running, sorry if I'm duplicating, it would be great to hear of any quotes that ring true for others here.
Thanks,
Remedy
