audio book is very useful for me to listen on the train in the morning.
i was so influenced by audio book "everything in this world consists of hypothesis".
it notices me how our thoughts or feelings were made by hypothesis, and it can be changed by being conscious of that there is no "truth" in this universe. every principle or science or story that people thought truth in the past can not be truth now.
Thinking outside the box is very important to live a wonderful life, I think.
