In a recent comment on The Edge, Prof. Ravi Arapurakal suggested there are two types of creativity, viz: creativity for generating anything new, and creativity for fulfilling a purpose.
I'd like to rename those, Creativity Pure and Applied, and discuss them both here, getting into some tips and techniques.
Applied creativity is creativity that is pointed in the direction of problem solving, where the problem is known in advance.
Pure creativity is free-roaming, and typically introduces materials we are aware of but haven't brought into consciousness -- often in response to some deep-seated concern or issue that has been "in the back of our mind" for some time.
