Pleasure comes more from making progress toward goals than from achieving them

I quote from Jonathan Haidt:

The final moment of success is often no more thrilling than taking off a heavy backpack at the end of a long hike. If you went on the hike only to feel that pleasure, you are a fool. Yet people sometimes do just this. They work hard at a task and expect some special euphoria at the end. But when they achieve success and find only moderate and short-lived pleasure, they ask is that all there is? They devalue their accomplishments as a striving after wind. We can call this the progress principle: Pleasure comes more from making progress toward goals than from achieving them.

Pleasure comes from the progress towards the goal. If you do not stop to look around while trying to achieve our goal, then you have lost a lot in life.
