You are what you see

We all know that in a materialistic way we are what we eat. At least, our bodies are what we eat. But I think our minds and personalities are what we see. If you see the world as boring and uninteresting, then there's a good possibility that slowly you will become boring and uninteresting. On the other hand, if you see the world as challenging, compassionate, and full of love, you too will slowly become a challenging, compassionate, and loving person.
