What is positive thinking?

“The greatest discovery of all time is that a person can change his future by merely changing his attitude.”-Oprah Winfrey

Wouldn’t it be great, if positive thinking was a way of life?
Positive thinking is a mental and emotional attitude that focuses on the bright side of life and expects positive results.
A positive person anticipates happiness, health and success, and believes he or she can overcome any obstacle and difficulty.
With a positive attitude we experience pleasant and happy feelings. This brings brightness to the eyes, more energy, and happiness. Our whole being broadcasts good will, happiness and success. Even our health is affected in a beneficial way. We walk tall, our voice is more powerful, and our body language shows the way we feel.
Positive and negative thinking are contagious.
We affect, and are affected by the people we meet, in one way or another. This happens instinctively and on a subconscious level, through words, thoughts and feelings, and through body language.
Is it any wonder that we want to be around positive people, and prefer to avoid negative ones?
People are more disposed to help us, if we are positive, and they dislike and avoid anyone broadcasting negativity.
Negative thoughts, words and attitude, create negative and unhappy feelings, moods and behaviour. When the mind is negative, poisons are released into the blood, which cause more unhappiness and negativity. This is the way to failure, frustration and disappointment.
