its basicly a qoute from the dune novals... in plain english it means if i don't fear i can do anything or nothing is impossible with fear aside. i wouldnt worry about it too much tho its just a cool quote
I hate when people try to sound deep, but really are just saying meaningless bullshit. Like Robert Frost's The Road Not Taken. What a crock of shit.
Fearing is impossible if fear is put aside, and therefore you limit yourself very, very much. But one thing that is definitely possible, and probably certain, if you ignore your fears: Mistakes.
