“The beginning of wisdom for a programmer is to recognize the difference between getting his program to work and getting it right. A program which does not work is undoubtedly wrong; but a program which does work is not necessarily right. It may still be wrong because it is hard to understand; or because it is hard to maintain as the problem requirements change; or because its structure is different from the structure of the problem; or because we cannot be sure that it does indeed work.”

— Michael A. Jackson

“Successful problem solving requires finding the right solution to the right problem. We fail more often because we solve the wrong problem than because we get the wrong solution to the right problem.”

Russell L. Ackoff (1919–2009) Scientist

“The fact is, people work hard and rely on Food Stamps—or SNAP Program—to be able to feed their families. When they work full-time they still live in poverty. That's wrong in our nation. Students who are losing hope because of the difficulty of finding jobs in this tough economy. What we need to do, what is best for America, is to raise wages, create jobs, and then we will move forward. Hard-working people are trying their best, but those who hold on to capital are not sharing the wealth, and there is the problem.”

“Computers are great because when you're working with them you get immediate results that let you know if your program works. It's feedback you don't get from many other things.”

“This is the Unix philosophy: Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.”

“Morality does not come from the clouds; it is born of human want and human experience. We need no inspiration, no inspired work. The industrious man knows that the idle has no right to rob him of the product of his labor, and the idle man knows that he has no right to do it. It is not wrong because we find it in the Bible, but I presume it was put in the Bible because it is wrong.”

Robert G. Ingersoll (1833–1899) Union United States Army officer

“If you marry the wrong person for the wrong reasons, then no matter how hard you work, it's never going to work, because then you have to completely change yourself, completely change them, completely — by that time, you're both dead.”

Anne Bancroft (1931–2005) American actress

On successful marriage. Associated Press interview (1997).
Context: First of all, you have to marry the right person. If you marry the wrong person for the wrong reasons, then no matter how hard you work, it's never going to work, because then you have to completely change yourself, completely change them, completely — by that time, you're both dead. So I think you have to marry for the right reasons, and marry the right person.

“101 Dealing with failure is easy: Work hard to improve. Success is also easy to handle: You've solved the wrong problem. Work hard to improve.”

“But we're still left with structural or compositional elements. The problems aren't any different. I still have to compose a picture, and if you make an object [as Donald Judd does] you have to organize the structure. I don't think our work that radical in any sense because you don't find any really new compositional or structural element. I don't know if that exists. It's like the idea of the color you haven't seen before. Does something exist that's as radical as a diagonal that's not a diagonal? Or a straight line or a compositional element that you can't describe?”

Frank Stella (1936) American artist

quote from Stella, reacting in the artist-talk on Donald Judd who emphasis the 'whole' of an art work
