When you were going to school as a child, you probably had teachers who helped mold and shape you into the person you are today. Some of them taught you about math and science, others taught you about art and history and still others taught you about community service or spirituality.

Even now, as an adult, we all need teachers, Dr. Robin says. Even when you think you know it all or your mind is made up on a given subject, we still need people who we can learn from—friends, neighbors and co-workers who can open our eyes to new ways of doing things or give us a fresh perspective on life, she says.

Dr. Robin says that recognizing the teachers in your life means you're ready to learn something new and you're open to growing as a person. "You're still willing to open your heart and to actually reopen your mind to at least consider that maybe there's a better way of doing things than the way you've been doing things," she says.
