If you fall in love with an outcome, you will never notice that the world around you is moving, that the context is ever changing, and that the outcome, in the end, does not provide that sense of reward you had anticipated.
If instead you fall in love with the journey, you are in the present, here and now. You see the changes, you notice the details, you are awake and ready, you have a place to fall back to when the unexpected becomes reality.
The journey is just a superior companion.
