When I was younger the destination was almost always on the top of the list. Going through difficult patches sometimes motivated me because I knew the prize would be more gratifying.
Now, gratification has given way to fulfillment and the journey is incredibly more important than the destination. The difficult patches now motivate me as I have chosen to welcome them as part of the journey and I view them as opportunities to learn more about myself and my contribution to the world.
Great way to pose this question!
