Imagine that there is a common language. This common language will allow us to communicate effectively, with friends, family, associates and workmates.  By understanding this language, it will help us to recognise and value each others positive and negative aspects that will in turn aid with personal development and empowerment of our general every day lives.  Often in life we can meet with someone whom we immediately click with while on other occasions we meet someone and our hackles are immediately up.  By understanding ourselves first then we can begin to understand all our relationships.
