Thinking Toys are mental moves that help us solve problems. They can help us get unstuck. We’d like our minds to have effortless subconscious access to these tools. However, this requires regular practice until they’re installed.
With practice, the process of “thinking” can automatically run through explicit moves that get us better solutions.
