Do Unto Others As You Would Want Done Unto You

Anyone who has been to preschool or kindergarten knows this rule. Here's a fact, not everyone follows this rule, in fact most people forget about this rule in their daily lives.
Truth is everyone needs some act of kindness everyday. If people could live their lives by this simple rule, in general I believe peoples days will seem better. People may feel that it's easier to trust one another. Not only that but people will be happier and live life respecting themselves and one another.
It's quiet bothersome that people lose sight of this simple rule. It's a cycle, one person hurts or damages someone, so when they do it to someone else it's their way of justifying what was done to them.
Everyone makes mistakes and can become greedy and selfish. It's not wrong to want things to go right for you, but is it so hard to treat people with respect. The answer should be no, just place yourself in that persons shoes. Treat people the way they should be treated and your life can have some fulfillment.
So they says "do unto others as you would want done unto you" and I agree, just hopefully people start doing it.
