You can’t do it alone, no one ever has and no one ever will. Think about getting dressed in the morning without a mirror: a very risky proposition. You may feel like you look good and you may walk out the door with full confidence in your appearance. But you can’t really know if how you feel matches how others see you. And even a mirror only gives you feedback in two dimensions. To really know how you look and, more importantly, the impact you have on others, you need a three-dimensional perspective: another set of eyes, that can see your situation in multiple dimensions. We all have blind spots and we need someone we can trust to give honest, helpful feedback.
