A slight paraphrase of a line from Crosby Stills Nash & Young's song, "Almost Cut My Hair from the album, Deja Vu. (The original reads, "But I'm not giving in an inch to fear.") I like both its defiance and its recognition that fear often compels us to act in ways we'll later regret.
In view of the phrase's inherent defiance, most double-sided products such as apparel feature a raised fist graphic on the obverse side.
