Stanford's business school uses an improv game where students rapidly list items in a category, prioritizing speed over accuracy. This exercise demonstrates that generating a high volume of ideas, even imperfect ones, is the most effective path to finding the best idea, as the best concepts often emerge late in the process.

Breakthroughs often occur in routine environments like the shower or during a walk. These activities promote what psychologists call "divergent thinking," where the relaxed mind makes novel connections. This scientific process can be intentionally triggered to solve complex problems and foster creativity.

Starting with limitations like budget and feasibility (convergent thinking) kills growth and leads to repetitive outcomes. You must begin with an expansive, divergent phase to generate a wide pool of ideas before applying any constraints.

Contrary to being restrictive, journaling prompts can be liberating. They challenge you to explore topics and perspectives you wouldn't naturally gravitate towards, twisting your mind “out of its usual ruts.” Even writing about your resistance to a prompt can yield surprising insights.

Alternating between solving hard, practical problems and engaging in "unrelentingly creative" playful projects creates a beneficial feedback loop. This "zigzagging" allows you to question core assumptions in your serious work and apply creative insights gained from taking the constraints off.

A core ideation technique is to ask, 'What if this but for that?' The key is to connect two concepts that are very far apart (e.g., Japanese architecture and hand soap). The greater the distance between the two, the more 'creative tension' and differentiation the final idea possesses.

To avoid generic brainstorming outcomes, use AI as a filter for mediocrity. Ask a tool like ChatGPT for the top 10 ideas on a topic, and then explicitly remove those common suggestions from consideration. This forces the team to bypass the obvious and engage in more original, innovative thinking.

The most crucial part of creativity is letting ideas "simmer" in the unconscious. After gathering information, step away from the problem completely. Engage in unrelated activities. This allows your mind to make novel connections you can't force through active thought.

Improving imagination is less like a painter adding to a blank canvas and more like a sculptor removing material. The primary task is to forget expected answers and consensus reality. This subtractive process uncovers the truly novel ideas that are otherwise obscured by convention.
