No one is born into this world automatically knowing how to do things or how to live life. We are all taught by someone. Our principles, ethics, work habits, perception of home and family, mannerisms, as well as all other aspects of life are things that we learn from others.
In light of that, it's important to realize that whether you are conscious of it or not, you are a teacher, a role model, and an example for somebody. Everything you do is teaching someone something. Think of those with whom you associate everyday¾your children, relatives, friends, and colleagues. How you carry yourself, how you say things, how you live your life¾all of these things are examples that teach others.
Think of someone whom you enjoy being around. What makes him or her so pleasant? What are the person's qualities? What is it the person exudes that makes you feel so good around him or her? Is there something you can learn from the person and incorporate into your own character in order to exude that same feeling to others? Perhaps by you learning the specific qualities and characteristics possessed by the person, you can then teach someone else and pass on those particular qualities.
Learning and teaching go hand in hand. The things you learn today, you will teach to others tomorrow, be it through word or example. Be conscious of the fact that somebody is looking to you for an example. Somebody is looking to you for the "how-to's." Be aware of what you are learning and what you are teaching because it will influence those around you. Ask yourself, "What is it that others can benefit from by watching me? How do I carry myself? Do I walk around looking like I've been sucking on lemons all night? Or, do I walk around with the attitude, 'Yes, today is my day!'"
Life is about growing and investing in others. To continue growing involves continual learning. We should never get to the point where we believe we are too old or too set in our ways to learn and to grow. Our experience, wisdom, and even attitudes toward life can be a wonderful, positive influence and investment into the lives of others.
