Instead of thinking there are real interests versus momentary ones (as if those momentary ones are not also real or true), our time and energy are better spent encouraging and supporting the interests that our kids actually do have.
Picture a large piece of paper with circles of all sizes drawn all over it. Each circle represents an interest. A kid moves from circle to circle—they are like stepping stones. The child creates his or her own path by moving from one stepping stone to another. Some are part of a path that goes straight to some ultimate goal or achievement, others are part of paths that meander and let the person have a variety of experiences. Some are part of paths that twist and turn. Sometimes the kid sits on one of them for a really long time. Sometimes the path leads away from the current interest to something seemingly unrelated. And so on.
Looking back, we can often see the path pretty clearly. But we can't look ahead and know what the path is going to be.
