My husband, who was a joiner, is currently making a cabin bed with desk for our wee granddaughter. In order to involve her, he asked her to draw up plans for how she saw it looking. Out in the garage he let her help measuring the slats for the bed and I heard him advise her - “Measure twice, cut once”.
My advice would be “Let sleeping dogs lie”.
What four words of advice would you like to pass on?
