“The mind can go either direction under stress—toward positive or toward negative: on or off. Think of it as a spectrum whose extremes are unconsciousness at the negative end and hyperconsciousness at the positive end. The way the mind will lean under stress is strongly influenced by training.”
― Frank Herbert, Dune

“Without change something sleeps inside us, and seldom awakens. The sleeper must awaken.”
― Frank Herbert, Dune

“I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain.”
― Frank Herbert, Dune

“Our doubts are traitors,
and make us lose the good we oft might win,
by fearing to attempt.”
― William Shakespeare, Measure for Measure
