What was the reason (or reasons) why this athlete or this group of athletes first started to participate in this particular sport? What energizes their effort hour after hour, day after day, season after season? Why do these athletes practice one particular sport rather than another? Why are they practising now rather than, say, hanging out with their friends? When they do practice, why do these athletes quit for the day, or quit during their lifetimes? These same questions can be asked of children as they read books: Why begin? Why continue past the first page? Past the first chapter? Why pick that particular book? Why stop reading? Will their reading continue in the years to come? For a more personal example, let me ask, Why did you begin to read this book today? Will you continue reading to the end of this chapter? Will you continue reading until the end of the book? If you do stop before the end, then why will you stop? After reading, what will you do next? Why? The discussion in Box 1 expands on the quest to explain why we do what we do.
