If you want to think better (which, I know, isn’t on many people’s to-do list, but it should be) you have to think differently.
How do you do that?
One way is to inspect the object of your thought from many different angles.
Imagine a square. It has one face. Now move to the left. You see two faces. Now move over to the right. You see a third face. Come back to the middle and drop down. You see a fourth. Now rise upwards. You see a fifth. Now transport yourself right to the other side. You see a sixth face.
What looked like a square from one angle was in fact a cube with six different faces.
And the only reason you were able to discover that was because you changed the angle from which you looked at the shape.
