An old adage a friend of mine repeated to me when he was a journeyman carpenter a long while back: “Measure twice, cut once.”

It means when cutting boards while making something, best to measure where you are supposed to cut twice before actually making the cut, since you really can’t take the cut back once it’s done.

A similar rule might well apply to doing transactions on a computer system. Also when printing soft copy documents to paper.

For optimal efficiency, check your work twice before executing.

Check your work, it’s your after all, reflection of you, your doing, check twice then cut, execute,

Make it GOOD.
