An undirected journey is one where we evaluate options as we come across them, and make decisions on the go. It is like going on a road trip with no particular destination in mind.

A directed journey, on the other hand, is one where we are clear about where we want to go and then evaluate the options that we come across in that context. And choose the ones that take us where we want to go. It is like hiking up a hill on an unmarked trail, where the destination is clear but the path isn't. 

Undirected journeys can lead us to interesting places that we never imagined we would go to. If we're lucky. 

But they are far more likely to lead us to not so interesting places.

Directed journeys, on the other hand, have a higher probability of taking us to interesting places. We might still get lost along the way and never make it to the destination we directed ourselves towards, which makes up the remaining probabilities.

A worse option than both, though, is to take a directed approach to a destination we know we won't fully enjoy.
