When you are riding high, share the altitude with as many other writers as you can. Drop names in interviews. Share the spotlight with other books. Be appreciative of the attention and turn the focus back to your peers who might be feeling low. Trust me, this pays off in so many ways.

It’s more like those ground fountains that spout water from different spots: when someone else’s fountain bursts forth, be thankful the water is still flowing and that someday soon, it will be your turn.
