Answer:
First, you feel ecstatic that you accomplished what you set out to accomplish! It feels great! Your success is tangible (or visible) and you feel so proud of yourself. And then the feeling fades.
Success is not a permanent state; you must keep moving towards it. Every time you reach success, it stays for a while, lets you pet it like it’s a dog, and then it races ahead for you to start running again.
When you need to take the smallest step imaginable, all you’ve got to do is take that step. The victory still feels like achieving a huge goal, but just “cracking the seal” gives you the momentum to start flying.
