" Is man's destiny determined by the vicissitudes of environment or free will? I argue that it is free will, because what we think, what we dwell upon in our heads, whether it be fears or dreams, has a direct effect upon the physical world. The more you think about your downfall, your ruin, the greater the likelihood that it will occur. And conversely, the more one thinks of victory, the more likely one will achieve it. "
