I just read a great book that has some timeless ideas to help your family, friends, those you work with, or children in your care to work together in harmony.

Steven Covey names the 7 Habits of Highly Effective People. They are:
Be Proactive - Take initiative. Don't blame others for your actions. Be good, even when no one is looking.
Begin with the end in mind - Plan ahead and set goals. Do things that make a difference. Be a good citizen.
Put first things first - Do the have-tos, then the want-tos. Be disciplined and organised.
Think win-win - Balance getting what you want with what others want. Look for a third alternative.
Seek first to understand, then to be understood - Listen to other people's ideas and feelings without interrupting. Look people in the eyes when talking.
Synergise - Value other people's strengths and learn from them. Team with others to create better solutions for problems. Be humble.
Sharpen the Saw - Take care of your body by eating right, exercising, and getting sleep. Spend time with family and friends. Find meaningful ways to help others.
Most of us, probably do most of these things. Just reading it a different way can remind us to keep these things happening in our day to day lives. Food for thought!
