As a fantasy literature enthusiast, I've noticed the phrase 'vim and vigor' isn't commonly used in popular fantasy book series, but the essence of what it represents—energy, vitality, and spiritedness—is often embodied in characters and themes. For instance, in 'The Stormlight Archive' by Brandon Sanderson, characters like Kaladin and Shallan exude a relentless drive and determination that captures the spirit of 'vim and vigor.' Similarly, in 'The Kingkiller Chronicle' by Patrick Rothfuss, Kvothe's boundless curiosity and passion for life mirror this concept.
Some series, like 'The Wheel of Time' by Robert Jordan, showcase characters who possess an unyielding willpower and enthusiasm, which aligns with the idea of 'vim and vigor.' While the exact phrase might not appear, the underlying energy and dynamism are prevalent in many fantasy narratives. The genre thrives on characters who push boundaries, overcome odds, and radiate an infectious zest for life, even if the words 'vim and vigor' aren't explicitly stated.
