"One of the saddest observations I've made centers around how reluctant many of us are to learn from the people closest to us --- our parents, spouses, children, and friends. Rather than being open to learning, we close ourselves off out of embarrassment, fear, stubbornness, or pride. It's almost as if we say to ourselves, "I have already learned all that I can (or want to learn) from this person; there is nothing else I can (or need to) learn".
"I have tried to remain open to the suggestions of my friends and family. In fact, I have gone so far as to ask certain members of my family and a few of my friends, "What are some of my blind spots?" Not only does this make the person you are asking feel wanted and special, but you end up getting some terrific advice. It's such a simple shortcut for growth, yet almost no one uses it".
