At this very moment, as I hear a knock-knock-knocking somewhere, I look out my window and see this gorgeous woodpecker! It's pecking on my wooden window frame and I think about the relation between life (i.e. energy) and motivation. What motivates a woodpecker to peck?
When we answer this kind of question related to our own "pecks", we find out what motivates us in life. Because we are not birds, our motivations may be related to more than instincts and needs. We are, after all, passionate animals!
