When you make a mistake, you take responsibility for it.
President John F. Kennedy assumed full responsibility for his role in authorizing at the Bay of Pigs invasion in April 1961. The ill-fated invasion, which failed to overthrow Fidel Castro, was initially planned by the Eisenhower administration. Kennedy did not make excuses.
People respect a leader who assumes responsibility for their actions. Contrary to what those who deflect blame believe, showing responsibility for when things go wrong is actually a sign of strength.
How so?
A leader who stands up and takes blame for the actions of subordinates is a leader who knows him or herself.
An executive who exempts himself from blame when things go wrong is a person that cannot understand what it takes to lead because they lack one attribute essential to leadership: integrity!
