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.
A negative turn of events is not inherently bad. A positive turn of events is not inherently good.
You ought to be able to see the good in the bad as well as the bad in the good. Not to be detached from reality. Not to be problem child or the naïve dreamer. Not to stay away from grief and joy at all costs. But to be able to appreciate the power that you have to turn the narrative around.
