From Developmental Editing by Scott Norton:
Few pleasures are as great as the taste of a fresh idea. A new insight melts in the brain like chocolate on the tongue. Whether the insight is unprecedented in human history or news only to yourself doesn’t matter; the first time a thought occurs is always magic.
That magic is so fickle, perishable. I always find the strong desire to capture as much of it as possible, and the more I can horde upfront the better chance I have of making it to the finish line of anything.
