Charles F. Kettering (1876-1958), president of the General Motors Research Corporation, wrote in “Education Begins at Home” for The Reader’s Digest of February 1944:
 
“We are prone to toss at our children the finished products of man’s achievements — the radio, telephone, a lifesaving medicine — without telling them about the painful processes by which these miracles came into being. We seldom take the trouble to explain that every great improvement in aviation, communication, engineering or public health has come after repeated failures. We should emphasize that virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. The only time you don’t fail is the last time you try something, and it works. One fails forward toward success.”
 
“Failures are finger posts on the road to achievement” has been printed on many posters. The author C. S. Lewis (1898-1963) has been incorrectly credited with Kettering’s saying since 2005.

Charles Franklin Kettering (August 29, 1876 – November 24 or 25, 1958) was an American inventor, engineer, businessman, and the holder of 186 patents. He was a founder of Delco, and was head of research at General Motors from 1920 to 1947. Among his most widely used automotive developments were the electrical starting motor and leaded gasoline. In association with the DuPont Chemical Company, he was also responsible for the invention of Freon refrigerant for refrigeration and air conditioning systems. At DuPont he also was responsible for the development of Duco lacquers and enamels, the first practical colored paints for mass-produced automobiles. While working with the Dayton-Wright Company he developed the “Bug” aerial torpedo, considered the world’s first aerial missile. He led the advancement of practical, lightweight two-stroke diesel engines, revolutionizing the locomotive and heavy equipment industries. In 1927, he founded the Kettering Foundation, a non-partisan research foundation.

Even after you’ve succeeded, the worst stretch often begins.

Thought of the Day from Lightworker
Virtually nothing comes out right the first time.
Failures, repeated failures,
are finger posts on the road to achievement.
The only time you don’t want to fail is the
last time you try something…
One fails forward toward success.
