Failure refers to the state or condition of not meeting a desirable or intended objective, and may be viewed as the opposite of success. Product failure ranges from failure to sell the product to fracture of the product, in the worst cases leading to personal injury, the province of forensic engineering.

Thomas J. Watson is attributed with saying "If you want to succeed, double your failure rate". Wired Magazine editor Kevin Kelly likewise explains that a great deal can be learned from things going unexpectedly, and that part of science's success comes from keeping blunders "small, manageable, constant, and trackable". He uses the example of engineers and programmers who push systems to their limits, breaking them to learn about them. Kelly also warns against creating a culture (e.g. school system) that punishes failure harshly, because this inhibits a creative process, and risks teaching people not to communicate important failures with others (e.g. Null results).

The criteria for failure are heavily dependent on context of use, and may be relative to a particular observer or belief system. A situation considered to be a failure by one might be considered a success by another, particularly in cases of direct competition or a zero-sum game. Similarly, the degree of success or failure in a situation may be differently viewed by distinct observers or participants, such that a situation that one considers to be a failure, another might consider to be a success, a qualified success or a neutral situation.

Adam Kreek (born December 2, 1980) is a Canadian rower. Born in London, Ontario, he was a student at the University of Victoria where he met his wife Rebecca. He won the gold medal at both the 2003 and 2002 world championships for Canada's men's eight team in Milan, Italy and Seville, Spain respectively. At the 2004 Summer Olympics, Kreek competed with the Canadian men's eight, who were widely expected to win a medal but ultimately finished in fifth place. After the Olympics he moved to Stanford University to complete a degree in Geotechnical Engineering and Hydrology and continue his rowing career there under Coach Craig Amerkhanian. In 2005 Kreek took the summer off to get married and spend time with his wife. Kreek coached at Stanford Rowing Center in 2006 and 2007 for the Junior Crew.

He won a gold medal at the 2008 Summer Olympics in the men's eights with Andrew Byrnes, Kyle Hamilton, Malcolm Howard, Kevin Light, Ben Rutledge, Dominic Seiterle, Jake Wetzel and cox Brian Price. Kreek's singing of O Canada at the medal ceremony was cited as an inspiration by Simon Whitfield, who won a silver medal in the triathlon. Whitfield wrote "Sing like Adam Kreek" on the handlebars of his bicycle and repeated "Sing like Kreek" to himself near the end of the race.

Barbara Ann Corcoran (born March 10, 1949 in Edgewater, New Jersey) is an American businesswoman, investor, speaker, business consultant, syndicated columnist, author, and television personality. As a television personality, she is a "Shark" investor on ABC's Shark Tank.

She graduated from St. Thomas Aquinas College with a degree in education in 1971. After graduation, she taught school for a year, but soon moved on working various jobs including a side job renting apartments in New York City. She wanted to be her own boss, and in 1973 co-founded a real estate business called The Corcoran Group with her wealthy boyfriend, who fronted a $1000 loan (approximately $5,000, inflation-adjusted). In the mid-1970s she also began publishing The Corcoran Report on real estate data trends in New York City.

In 2001, Corcoran sold her business to the giant NRT Incorporated for $66 million.

She is a columnist for More Magazine, The Daily Review, and Redbook, has written books, and has been featured in various shows such as Larry King Live.

Michael Jeffrey Jordan (born February 17, 1963) is a retired American professional basketball player, active entrepreneur, and majority owner of the Charlotte Bobcats. His biography on the National Basketball Association (NBA) website states, "By acclamation, Michael Jordan is the greatest basketball player of all time." Jordan was one of the most effectively marketed athletes of his generation and was considered instrumental in popularizing the NBA around the world in the 1980s and 1990s.

After a three-season career at the University of North Carolina at Chapel Hill, where he was a member of the Tar Heels' national championship team in 1982, Jordan joined the NBA's Chicago Bulls in 1984. He quickly emerged as a league star, entertaining crowds with his prolific scoring. His leaping ability, illustrated by performing slam dunks from the free throw line in slam dunk contests, earned him the nicknames "Air Jordan" and "His Airness". He also gained a reputation for being one of the best defensive players in basketball. In 1991, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 and 1993, securing a "three-peat". Although Jordan abruptly retired from basketball at the beginning of the 1993–94 NBA season to pursue a career in baseball, he rejoined the Bulls in 1995 and led them to three additional championships (1996, 1997, and 1998) as well as an NBA-record 72 regular-season wins in the 1995–96 NBA season. Jordan retired for a second time in 1999, but returned for two more NBA seasons from 2001 to 2003 as a member of the Washington Wizards.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.
