Brooks "Design of Design"

"He who seeks originality will often find novelty, but not great design."

The Pet Rock was very original, but not necessarily a great thing.

As BJC said, good design begins by asking questions.
What would you want to create? The most agile? The fastest? The most powerful pusher? The best balance? Even "most original" would require knowledge of what others have done. Otherwise, you would find yourself talking about this great, original design that someone else ahs done.

Study "good" examples. What do you like about them? What do you not like about them? How could you/would you do things different?
