Nothing is more dangerous than to stop working. It is a habit that can soon be lost, one that is easily neglected and hard to resume. A measure of day-dreaming is a good thing, like a drug prudently used ... But too much submerges and drowns. Woe to the intellectual worker who allows himself to lapse wholly from positive thinking into day-dreaming. He thinks he can easily change back, and tells himself that it is all one. He is wrong! To substitute day-dreaming for thought is to confuse poison with a source of nourishment.
The technique of positive thinking is not a technique that transforms you. It is simply repressing the negative aspects of your personality. It is a method of choice. It cannot help awareness; it goes against awareness. Awareness is always choiceless.
I am absolutely against positive thinking. You will be surprised that if you don't choose, if you remain in a choiceless awareness, your life will start expressing something which is beyond both positive and negative, which is higher than both. So you are not going to be a loser. It is not going to be negative, it is not going to be positive, it is going to be existential.
