Research has found that novices disproportionately seek positive feedback, whereas experts seek negative feedback[0]. Would you rather be more like a novice, or more like an expert?
Doyen of entrepreneurs, Elon Musk, also advices entrepreneurial wannabes to seek negative feedback[1]:
"Always seek negative feedback, even though it can be mentally painful. They won't always be right, but I find the single biggest error people make is to ignore constructive, negative feedback."
