“Too often, the people we ask for feedback are nice but not kind. Kind people will tell you things a nice person will not. A kind person will tell you that you have spinach on your teeth. A nice person won’t because it’s uncomfortable. A kind person will tell us what holds us back, even when it’s uncomfortable. A nice person avoids giving us critical feedback because they’re worried about hurting our feelings. No wonder we think other people will be interested in our excuses.”
