I start by positing that most everyone operates as if they are the center of the universe.

And most everyone is motivated by self interest.

If you recognize and operate under these core principles you will best be able to negotiate the difficult twists and turns of life.

Harmony occurs when you find parallel interests with someone. Synergy is a good word.

Selfish is not a bad word.

However, all this goes out the window when we encounter those who do not fit into the above “most everyone” category!
