Live so that when your children
think of fairness, caring, and integrity, they think of you.
H. Jackson Brown, Jr.
I would say this quote is pretty straight to the point and self-explanatory. Model good behaviour. Not only to children, but to everyone around us, especially those that we have authority and/or influence over.
People will take you more seriously, and be more inclined to follow your lead and vision, if they see that you do not only talk the talk, but that you also walk the walk.
Be the change that you want to see. Use your actions and life, more than just your words to teach and inspire others.
