The Encyclopedia of Natural Medicine states that the largest part to your overall health is from your mental health. Having positive mental health gives us the motivation to do our best that we can and always striving to do better (Murray, Michael & Pizzorno, and Joseph: Encyclopedia of Natural Medicine (1998)(pgs. 17-19)(Revised 2nd Edition); Three River Press, New York.). Seeing the brighter side of things instead of the bad is just one way you can help your positive mental health. Keeping your thoughts positive will assist you in talking more positive. Positive people influence others to get into a healthier positive mental state of health. When a person is mentally healthy they are more equip to deal with reality and adapt to changes in a positive way. With good mental health comes good emotional as well as intellectual health, which aides in the problem solving of life events (Health the Basics, Pearson, 10th ed. pg29).
Positive Mental Attitude has been touched upon since the concept of free will, but the concept was first developed and introduced in 1937 by Napoleon Hill in the book Think and Grow Rich. The book never actually uses the term, but develops the importance of positive thinking as a principle to success. He, along with W. Clement Stone, later wrote Success Through a Positive Mental Attitude which defines positive mental attitude as "The right mental attitude... comprised of the 'plus' characteristics symbolized by such words as faith, integrity, hope, optimism, courage, initiative, generosity, tolerance, tact, kindliness and good common sense."
Electrical polarity (positive and negative) is present in every electrical circuit. Electrons flow from the negative pole to the positive pole. In a direct current (DC) circuit, one pole is always negative, the other pole is always positive and the electrons flow in one direction only. In an alternating current (AC) circuit the two poles alternate between negative and positive and the direction of the electron flow reverses.
In DC circuits, the positive pole is usually marked red (or "+") and the negative pole is usually marked black (or "-"), but other color schemes are sometimes used in automotive and telecommunications systems. On a car battery, the positive pole usually has a larger diameter than the negative pole.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
