Yes, It's hard to hear criticism.
When someone points out your flaws, your gut reaction is 'WTF?!' - or in business terms, 'defensiveness.'
Of course, you want to protect your ego. You want to explain yourself, prove them wrong, or even tell them to f* off. Tempting, isn't it?
But defensiveness kills growth. Pause. Breathe. Ask yourself: 'What can I learn from this - even though I hate it?' Growth starts the moment you listen instead of emotionally react.
Nothing to learn from it? That's also ok but still thank the person who gave you feedback.
