Lots of great material in this latest book, The Rules of Genius: An innovator's guide to creativity by Marty Neumeier.

Rule #32 is one of my favourites: SPEND LONG HOURS IN THE JOY ZONE.
An excerpt: "When your work contains an element of joy, you learn faster. This is called "ludic" learning, or learning by playing. [...] When you're happy, you're more creative. When you're unhappy, you lose access to your intuition. Happiness and creativity are mutually supportive. [...] Ludic learning is often the doorway to genius."
