1) Habits and thought patterns developed over time can block creativity by making us rigid in our thinking and less open to new ideas. Our tendency is to rely on what is known and familiar rather than exploring unfamiliar or unknown options.
2) As we gain experience, we develop mental categories to organize information, but these categories can also prevent insight if we only try to fit new problems into existing frameworks rather than considering wholly new approaches.
3) Many common obstacles to creativity arise from social and psychological factors that discourage behaviors like asking questions, taking risks, being different from others, or maintaining an openness to uncertainty. Overcoming these blocks requires recognizing how our default ways of thinking can interfere with creativity.
