Do not persist in folly. Some make a duty of failure and having started down the wrong road, think it a badge of character to continue.
[No proseguir la necedad. Hacen algunos empeño del desacierto, y porque comenzaron a errar, les parece que es constancia el proseguir.]
Baltasar Gracián y Morales (1601-1658) Spanish Jesuit priest, writer, philosopher

(Source (Spanish)). Alternate translations:Not to continue a Foppery. Some make an engagement of their mistakes: when they have once begun to fail, they think they are concerned in honour to continue.
[Flesher ed. (1685)]Do not follow up a Folly. Many make an obligation out of a blunder, and because they have entered the wrong path thinks it proves their strength of character to go in it.
[tr. Jacobs (1892)]Don’t persist in folly. Some people commit themselves to their errors. They act mistakenly and consider it constancy to go on that way.
[tr. Maurer (1992)]

You can’t go back and change the beginning, but you can start where you are and change the ending.
C. S. Lewis (1898-1963) English writer, literary scholar, lay theologian [Clive Staples Lewis]
(Spurious)
Not found in Lewis' writings, and not considered authentic. There is some similarity to this Lewis quotation. More discussion here:
Progress means getting nearer to the place where you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; and in that case, the man who turns back soonest is the most progressive.
C. S. Lewis (1898-1963) English writer, literary scholar, lay theologian [Clive Staples Lewis]

One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.
Carl Sagan (1934-1996) American scientist and writer

Long books, when read, are usually overpraised, because the reader wants to convince others and himself that he has not wasted his time.

Ignorance maketh most Men go into a Party, and Shame keepeth them from getting out of it.

It is a human inclination to hope things will work out, despite evidence or doubt to the contrary. A successful manager must resist this temptation. This is particularly hard if one has invested much time and energy on a project and thus has come to feel possessive about it. Although it is not easy to admit what a person once thought correct now appears to be wrong, one must discipline himself to face the facts objectively and make the necessary changes — regardless of the consequences to himself. The man in charge must personally set the example in this respect. He must be able, in effect, to “kill his own child” if necessary and must require his subordinates to do likewise.
Hyman Rickover (1900-1986) US Navy Admiral
Quoted in T. Rockwell, The Rickover Effect, Part 3, ch. 2, epigraph (1992)
