Wonder freely through the realms of imagination

Instructions

Practice thought experiments.
Thought experiments were the favorite mind game that Einstein used to do. A thought experiment permits you to test ideas in your mind. Nikola Tesla also said that he used thought experiments to create and optimize complete inventions in his mind before making them a reality. You could use it to test a bold idea that you have.
Work intermittently with other people.
It can be insightful to work alone, but you can also benefit from other people’s ideas by working together with them. Andrew Wiles corrected his brilliant proof, which he created alone, with the help of another mathematician.
Get bored more often.
Being bored permits your mind to enter a more diffuse mode of thinking, making you more creative.
