Do unto others etc.

If you have been brought up as Christian, you will be familiar with this principle. The usual interpretation of the phrase is to treat each other as you would like to be treated yourself.

However, consider this, the phrase goes beyond this slightly egocentric view. What it is actually saying is that you should treat other people as they would like to be treated; i.e in a way that pleases them. That way:
a) they will understand you better
b) they may even reciprocate this principle and you will understand them better

Don't forget, not everyone has the same world view as yourself and therefore by seeing the world through other people's eyes and having a flexible approach in treating people means you can get your message across much easier.
