You can look at life and say to yourself: “Life sucks and then you die.”
And you can look at life and say: "It's amazing! A human being consists of forty thousand billion cells. How can all these cells be synchronized? Every second is a miracle."
These two ways of looking at life is like looking at "Rubin’s vase"- both ways makes sense.
One part of you comes up with one kind of explanation, another part comes up with something else. One part of you can easily deceive the other part. Whom is cheating whom? Isn't all this strange? A human being have so many different voices in his head and what is even more strange, they change over the years. Nothing is permanent. There is no permanent you.
It is therefore important to remind yourself, over and over again, that none of these explanations is the truth. They are explanations, mental speculations, concepts, theories, ideas, stories, maps, castles in the air, call them what you want, but don’t mix them up with yourself or the reality. Don't believe everything you hear from yourself. Don't trust yourself completely.
