The real world is chaotic and random. To build anything complex and meaningful, we need to notice patterns. We must create another reality — an intentionally delusional one — where everything reminds us of our purpose and where numerous patterns help us progress.
You first create the world you want in your mind. Then, you manifest it into a delusional world around you. After that, you live there, investing time and effort, and it is built, brick by brick, before your eyes.
