A method for solving problems or creating new ideas is to use a new perspective.
There are many ways to take a new perspective.
If you change your location you will think differently. This is why many problems are solved in the shower. Find different locations where you can create new ideas or solve problems such as coffee shops, nature hikes, and walks. Even changing your clothes can make you think differently about a problem.
Another way to change perspective is to look at a problem from another person’s perspective. If you are having a disagreement, take the other person’s side and debate from that perspective. You can also look at things from your future self’s perspective, or from the perspective of someone you admire.
For ideas, you can add the perspective of some unrelated idea. What you will find is there is always some connection between any two ideas.
The whole idea is to take the problem or idea outside of yourself so that you can intellectually walk around the problem or idea and look at it from many different perspectives.
