Hope is the emotional state which promotes the belief in a positive outcome related to events and circumstances in one's life. Despair is the opposite of hope. Hope is the "feeling that what is wanted can be had or that events will turn out for the best" or the act of "look[ing] forward to something with desire and reasonable confidence" or "feel[ing] that something desired may happen". Other definitions are "to cherish a desire with anticipation"; "to desire with expectation of obtainment"; or "to expect with confidence". In the English language the word can be used as either a noun or a verb, although hope as a concept has a similar meaning in either use.

Dr. Barbara L. Fredrickson, Principal Investigator of the Positive Emotions and Psychophysiology Lab and Professor at the University of North Carolina, Chapel Hill, argues that hope "...comes into play when our circumstances are dire", when "things are not going well or at least there’s considerable uncertainty about how things will turn out". She states that "[h]ope literally opens us up...[and] removes the blinders of fear and despair and allows us to see the big picture [, thus allowing us to] become creative" and have "[b]elief in [a] better future".

Eduardo "Lalo" Guerrero (December 24, 1916 – March 17, 2005), was a Mexican-American guitarist, singer and farm labor activist best known for his strong influence on today's Latin musical artists.

Guerrero was born in Tucson, Arizona, one of 21 siblings (although only nine survived). His father worked for the Southern Pacific Railroad. Guerrero left his hometown to pursue his dream in music. He says that he gives his mother all the credit for his musical talent, and Lalo even stated that she taught him to "embrace the spirit of being Chicano". Lalo, in time exceeded even his wildest dreams as a musician, writer and performer for more than six decades, gaining worldwide recognition as the father of "Chicano Music". His first group, Los Carlistas (the trio included Chole Salaz and Joe Salaz), represented Arizona at the 1939 New York World's Fair, and performed on the Major Bowes Amateur Hour on radio.

He moved to Los Angeles in the 1940s, and had a few uncredited roles in movies, including Boots and Saddles and His Kind of Woman. He recorded for Imperial Records and fronted the Trio Imperial. He also formed his own orchestra and toured throughout the Southwest. He performed at the La Bamba club in Hollywood, a place frequented by the biggest stars in the movie business. In the 1960s, he bought a night club in Los Angeles and renamed it Lalo's.

Clannad are an Irish band formed in 1970 in Gaoth Dobhair, County Donegal. Their music has been variously described as bordering on folk and folk rock, traditional Irish, Celtic and New Age, often incorporating elements of an even broader spectrum of smooth jazz and Gregorian chant. After twelve years of success in the folk music industry, they shot to international recognition in 1982 with the release of the "Theme from Harry's Game", becoming the most successful band in the Celtic music genre. They have won several notable awards throughout their career, including a Grammy, a BAFTA, an Ivor Novello and a Billboard Music Award.

Clannad are a family band composed of siblings Moya Brennan (Irish: Máire Ní Bhraonáin), Ciarán Brennan (Irish: Ciarán Ó Braonáin), Pól Brennan (Irish: Pól Ó Braonáin, who left in 1990 and rejoined in 2011) and their twin uncles Noel Duggan (Irish: Noel Ó Dúgáin) and Pádraig Duggan (Irish: Pádraig Ó Dúgáin). Their sister/niece Enya (Irish: Eithne Ní Bhraonáin) left the group in 1981 to pursue a solo career.
