Questions hijack the brain. The moment you hear one, you literally can’t think of anything else. And that can be a powerful tool.
What color is your house?
After reading that question, what were you thinking about? The obvious answer is the color of your house. Though this exercise may seem ordinary, it has profound implications. The question momentarily hijacked your thought process and focused it entirely on your house or apartment. You didn’t consciously tell your brain to think about that; it just did so automatically.
