âDedicatedâ Makes the Case for Choosing Something and Sticking With It When you purchase an independently reviewed book through our site, we earn an affiliate commission. Before reading âDedicated,â a new book by Pete Davis, I hadnât realized that the acronym YOLO â you only live once â wasnât always a celebration of doing something fleeting and reckless just for the thrill of it.
