“How do you ever know for certain that you are doing the right thing?”

“But how do you ever know that you know a person?”

Anita Shreve book The Pilot's Wife

“There is no such thing as duty. If you know that a thing is right, you want to do it. If you don't want to do it—it isn't right. If it's right and you don't want to do it—you don't know what right is and you're not a man.”

Ayn Rand (1905–1982) Russian-American novelist and philosopher

“Next to doing the right thing, the most important thing is to let people know you are doing the right thing.”

John D. Rockefeller (1839–1937) American business magnate and philanthropist

“How do you go on knowing that you will never again - not ever, ever - see the person you have loved? How do you survive a single hour, a single minute, a single second of that knowledge? How do you hold yourself together?”

Howard Jacobson book The Finkler Question

“When you do something that works you have a happiness, but I don't know if it's a feeling of power. Power is a frightening thing and that's not what I'm interested in. I want to do certain things and make them right in my mind and that's it.”

David Lynch (1946) American filmmaker, television director, visual artist, musician and occasional actor

“The truth of the matter is that you always know the right thing to do. The hard part is doing it.”

Norman Schwarzkopf (1934–2012) United States Army general

“If you don't know where you want to be in five years, how do you ever expect to get there?”

Jay Samit (1961) American businessman

“It's the movies that have been running things in America ever since they were invented. They show you what to do, how to do it, when to do it, how to feel about it, and how to look how you feel about it.”

Andy Warhol (1928–1987) American artist

“I don't know. It's been terribly hard for me. How do I know you won't do it again?'
'Nobody is ever quite sure of what they will do. You aren't sure what you might do.”

Charles Bukowski book Women
