Creativity is like a salmon.
The harder you try to grasp the slimy thing, the more it slips away, until the elusive beast finally escapes from your clutches all together and slaps you in the face as it leaps away, leaving you with nothing but a headache.
Confused? Fear not, friends. The book explains each step in loving detail. Did I forget to mention that this book is full of wonderfully drawn (not to mention dead useful) illustrations as well? That's always a plus. This book is always sitting on my desk, ready for whenever my muse is feeling drained. Buy yourself a copy. Go forth and create. You won't regret it.
P.S. I feel like my post turned into an advertisement, but hey, this book really is useful. I can't help showing it off to the world :)
