- "The only time you don't want to fail is the last time you try."
- "The only time you can't afford to fail is the last time you try."
- "The only time you don't fail is the last time you try something, and it works."
Quotations by:
Kettering, Charles F.
Logic is an organized way of going wrong with confidence.
Charles F. Kettering (1876-1958) American inventor, engineer, researcher, businessman
“Kettering’s Law,” from address before American Society of Mechanical Engineers (c. 1944)
Quoted in Heinlein, The Number of the Beast (1980). Alternately quoted:
- "Beware logic. Logic is an organized way to go wrong -- with confidence."
- Logic is an organized way to go wrong with confidence. We should all know by now that a logical course is not always the right one."
Sometimes referred to "Kettering's Observation."
Cited in Food Industries magazine, vol. 16 (1944), referring to the speech being "recent" (the magazine is also referred to as Food Engineering).
This site previously incorrectly attributed the quote to Iris Murdoch. That attribution seems to have been duplicated at some other sites, but was an error. I have also found citations to L. Walter Lundell and Karl Popper.
Another "Kettering's Law" that is referenced is: "Parts left out cost nothing, require no maintenance, and do not fail."
Every great improvement has come after repeated failures. Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. One fails forward toward success.

Whenever you look at a piece of work and you think the fellow was crazy, then you want to pay some attention to that. One of you is likely to be, and you had better find out which one it is. It makes an awful lot of difference.
