Metaphorically Speaking

At the beginning Jack goes north to Bear Mountain. He gets there and gets very upset. He starts yelling and crying about how he hadn't even started his journey.

Given Jack was probably in his mid twenties at the time, this mirrors the thoughts of many people of our age and maybe a little older. The idea that we have not yet begun, that this is not yet our journey is widespread against people in their late teens, despite the fact that what we do now affects us as much as anything we would do twenty years from now.
