Divergent Thinking

Or also called Brainstorming.

"Brainstorming programs are ways to stimulate people to increase the fluency, flexibility, and originality of their ideas and responses.

Produce as many ideas as possible.

Identify a key word and then try to generate as many synonyms as possible.

Have as many different ideas as possible.

Quantity is importatnt, but try to avoid redundancy.  Variety in conversation, in the selection of music, in a menu, is generally appreciated.  It pays off to learn how to alternate topics of conversation, types of restaurants, kinds of shows, ways of dressing.

Try to produce unlikely ideas

It is more difficult to learn how to think in original ways than to learn how to be fluent and flexible.  It requires cultivating a taste for quality that is not necessary in the other two.
