Something must be done, and believe me I am the one to do it!

Mother Taraza

So, the quote I was looking for. I found it. It was the Reverent Mother Taraza, from Frank Herbert’s Dune.
“In my estimation, more misery has been created by reformers than by any other force in human history. Show me someone who says, “Something must be done!” and I will show you a head full of vicious intentions that have no other outlet. What we must strive for always! is to find the natural flow and go with it.
