“A lazy man works twice as hard. My mother told that to me, and now I say it to my kids. If you’re writing an essay, keep it in the lines and in the margins so you don’t have to do it over.” – Gary Oldman (via Esquire)
This is true and describes the same dynamic as: “The poor man always pays twice.” (via Ken Rockwell)
Not being careful and intentional adds more work and cost.
