Never under-estimate the power of negative thinking: it's rational , practical and realistic and sets a person in preparing for an adverse downturn armed with some well-prepared solution- such a mindset is eminently admirable and enhances the person's chance of winning
while pipe-dreams dominate positive thinking with its slogan: ' You're born to be a victor' such is will o'-the-wisp -- the worst error!
Never ignore the strength of negative thinking it will bring positive thinking to its kneeling!
