Think about the people in your life who you know are going to love you no matter what you do. They are going to support you, be on your side, walk through it with you. They care.
Now think of everyone else. They may be an enemy, they maybe a parent, they may be an enemy-parent, they may be a co-worker, a critic, the list is probably long. They care, in all the wrong ways, because they probably don't care. They always have a comment, a look, an email, or something else.
What if your decision making was limited to thinking about the first group of people and not the second? How would it change what you do?
And, who in your life would count you as a member of that first group?
