Here is another way of interpreting this well-known quote:
"Seek not to change the world, but choose to change your mind about the world. What you see reflects your thinking. And your thinking but reflects your choice of what you want to see."
Instead of this meaning, that the world exists objectively and you must change your perception of it, so that you see it clearly....
What if it means...
What you see reflects your thinking. Change your mind and what you see will change, because YOU are MAKING the world. You are the cause of what's out there. YOU are the dreamer of the dream. Change your mind and the world must follow. Not just a change or a shift in your own perception, or a position of seeing it from a different vantage point. Instead, it's a position of recognizing and admitting that you have power OVER it and by changing your mind the world will change!
This means the exact opposite to what is it is commonly interpreted to mean. It is the sheer difference between merely changing how you perceive and attempting to accept and keep what is out there, verses realizing that you PUT the world there and by changing your mind you can be miraculous in changing it with the Power of God.
You don't think you have this power over the world because you believe heavily that it decides everything for you. That's being a victim of the world.
You are not supposed to just change your perception or INTERPRETATION of the world. You are supposed to realize that you have the power to create physical matter, to change objects, to heal sickness and undo death. That this world LITERALLY is coming from your mind and you have power over it.
