What you can't see, yet.
Our biases and blindspots can hide important information when we are making a decision. The perception deception, though, makes us believe that we can see everything. This leads to erroneous decision-making.
This is where generous feedback from others can help significantly. When the feedback giver is ready to do the emotional labour to understand where you seek to go, they can help you see the way that you can't see yourself.
And for us to allow the generous feedback giver to help, we have to learn to become generous feedback receivers ourselves. Instead of defending what we can see, we can learn to receive feedback on what we can't see, yet.
