If you’re lucky enough to get criticism from a respected source, listen to that shit carefully. Examine it closely, roll it around in your head for a few days, and sleep on it – ‘cuz here’s the thing: that person didn’t have to give you anything.
They chose, for no gain of their own, to offer you their thoughts. Only a fool would discard that without careful attention.
Now, you may or may not act directly based on their critique, but you need to appreciate this: you can’t get this from your friends, partner, family, or anyone else connected to you, because they’re biased. They know you.
But a respected third party?
That shit is gold.
