A woodsman was once asked, "What would you do if you had just five minutes to chop down a tree?" He answered, "I would spend the first two and a half minutes sharpening my axe."


That version is from “Objectives and Philosophy of Public Affairs Education” by C. R. Jaccard
more versions:
"Five minutes spent in sharpening the hoe, lawn mower, or even the shovel before work will save hours of time on the job, and the back won’t be so lame the next day." 1944 newspaper article in the Jefferson Herald, "Labor Savor"
"If I had five minutes to chop down a tree, I’d spend the first three sharpening my axe.” - 1960 advertisement attributing the quote to Abraham Lincoln
