Happiness is a mental or emotional state of well-being characterized by positive or pleasant emotions ranging from contentment to intense joy. A variety of biological, psychological, religious, and philosophical approaches have striven to define happiness and identify its sources.

Various research groups, including Positive psychology, endeavor to apply the scientific method to answer questions about what "happiness" is, and how we might attain it.

Philosophers and religious thinkers often define happiness in terms of living a good life, or flourishing, rather than simply as an emotion. Happiness in this sense was used to translate the Greek Eudaimonia, and is still used in virtue ethics.

Happiness economics suggests that measures of public happiness should be used to supplement more traditional economic measures when evaluating the success of public policy.

Happiness is a fuzzy concept and can mean many things to many people. Part of the challenge of a science of happiness is to identify different concepts of happiness, and where applicable, split them into their components.

Teddy Geiger (born John Theodore Geiger II on September 16, 1988) is an American singer-songwriter and occasional actor. He is known to play the guitar, bass, piano, drums and trombone.

In November 2011, Teddy announced that he is recording and releasing an exclusive new album The Last Fears through PledgeMusic.com.

Teddy Geiger was born in Buffalo, New York, later moving to Rochester, New York. He wrote his first song at the age of 10. Raised a Roman Catholic, Geiger attended McQuaid Jesuit High School through his junior year.

His first band was formed in 2005 under the name "Faction". This band played at several venues in Rochester, New York, winning a "battle of the bands" competition at the Water Street Music Hall. The band was headlined by Geiger's lyrics, vocals, guitar, and keyboard; other band members included drummer Ben Harmon, lead guitarist John Ryan, and bassist Daniel Beale. The band broke up in early 2005, following Geiger's signing with Columbia Records.

Teddy Geiger was first seen in national media as a finalist in VH1's In Search of the Partridge Family and earned credibility when touring with Hilary Duff as the opening act for her summer 2005 tour Still Most Wanted. His first single, "For You I Will (Confidence)", was officially released in February 2006. The song received positive reviews, being called "sweetly romantic" and said to contain "sophisticated lyrics", besides being nominated for "Best Love Song" in the 2006 Teen Choice Awards.

William Harrison "Bill" Withers, Jr. (born July 4, 1938) is an American singer-songwriter and musician who performed and recorded from 1970 until 1985. He recorded a number of hits such as "Lean on Me", "Ain't No Sunshine", "Use Me", "Just the Two of Us", "Lovely Day", and "Grandma's Hands". His life was recently the subject of the documentary film Still Bill.

Withers was born the youngest of six children in the small coal-mining town of Slab Fork, West Virginia. Raised in nearby Beckley, West Virginia, Withers was twelve years old when his father died. He enlisted with the United States Navy at age eighteen and served for nine years, during which time he became interested in singing and writing songs. Soon after his discharge from the Navy in 1965, he relocated to Los Angeles in 1967 for a musical career.

Withers worked as an assembler for several different companies, including Douglas Aircraft Corporation, while recording demo tapes with his own money, shopping them around and performing in clubs at night. When he debuted with the song "Ain't No Sunshine" he refused to resign his job because of his belief that the music business was a fickle industry and that he was still a novice compared to other acts.
