Optimism is a mental attitude that interprets situations and events as being best (optimized), meaning that in some way for factors that may not be fully comprehended, the present moment is in an optimum state. The concept is typically extended to include the attitude of hope for future conditions unfolding as optimal as well. The more broad concept of optimism is the understanding that all of nature, past, present and future, operates by laws of optimization along the lines of Hamilton's principle of optimization in the realm of physics. This understanding, although criticized by counter views such as pessimism, idealism and realism, leads to a state of mind that believes everything is as it should be, and that the future will be as well. A common idiom used to illustrate optimism versus pessimism is a glass with water at the halfway point, where the optimist is said to see the glass as half full, but the pessimist sees the glass as half empty.

The word is originally derived from the Latin optimum, meaning "best." Being optimistic, in the typical sense of the word, ultimately means one expects the best possible outcome from any given situation. This is usually referred to in psychology as dispositional optimism.

David Keith Lynch (born January 20, 1946) is an American filmmaker, television director, visual artist, comic book artist, musician and occasional actor. Known for his surrealist films, he has developed his own unique cinematic style, which has been dubbed "Lynchian", and which is characterized by its dream imagery, and meticulous sound design. The surreal, and in many cases violent, elements to his films have earned them the reputation that they "disturb, offend or mystify" their audiences.

Born to a middle class family in Missoula, Montana, Lynch spent his childhood traveling around the United States, before going on to study painting at the Pennsylvania Academy of Fine Arts in Philadelphia, where he first made the transition to producing short films. Deciding to devote himself more fully to this medium, he moved to Los Angeles, where he produced his first motion picture, the surrealist horror Eraserhead (1977). After Eraserhead became a cult classic on the midnight movie circuit, Lynch was employed to direct The Elephant Man (1980), from which he gained mainstream success. Then being employed by the De Laurentiis Entertainment Group, he proceeded to make two films: the science-fiction epic Dune (1984), which proved to be a critical and commercial failure, and then a neo-noir crime film, Blue Velvet (1986), which was highly critically acclaimed.
