“… and within five minutes I'd lost interest.”

July 3, 1998 Denver Post column

Innkeeper's wife
A Child is Born (1942)
Context: Life is not lost by dying! Life is lost
Minute by minute, day by dragging day,
In all the thousand, small, uncaring ways,
The smooth appeasing compromises of time,
Which are King Herod and King Herod's men,
Always and always. Life can be
Lost without vision but not lost by death,
Lost by not caring, willing, going on
Beyond the ragged edge of fortitude
To something more — something no man has ever seen.

To something more — something no man has ever seen.
You who love money, you who love yourself,
You who love bitterness, and I who loved
and lost and thought I could not love again,
And all the people of this little town,
Rise up! The loves we had were not enough.
Something is loosed to change the shaken world,
And with it we must change!

There is no indication that Einstein said this. According to Quote Investigator, the earliest publication of a quote similar was in a collection of articles about manufacturing in 1966, when an employee of the Stainless Processing Company wrote a piece titled "The Manufacturing Manager's Skills." The article attributed the quote to an unnamed professor at Yale, by saying, "If I had only one hour to solve a problem, I would spend up to two-thirds of that hour in attempting to define what the problem is." (See, 1966, The Manufacturing Man and His Job by Robert E. Finley and Henry R. Ziobro, "The Manufacturing Manager's Skills" by William H. Markle (Vice President, Stainless Processing Company, Chicago, Illinois), Start Page 15, Quote Page 18, Published by American Management Association, Inc., New York.

Disputed
Variant: If I had an hour to solve a problem I'd spend 55 minutes thinking about the problem and 5 minutes thinking about solutions.
