>>isn't it possible that there are deeper passions behind our decisions?
William,
Only rarely, I'd say. Many acts (I hesitate do say decisions) in our well-cared-for life arise from sheer boredom and a general drive to do something. Animal research has shown that if e.g. a bird has had no insects to peck at for a while it starts pecking at the empty ground, an instinctive movement, not because it is hungry.
Only a short timespan, in evolutionary terms, separates us humans from the epoch where we needed to be constantly active during waking hours, simply to survive.
