In life when we look at what makes people successful in their different endeavours one of the underling success factors lies in the goals they set. I believe if we want to maintain and improve our relationships it helps to consciously set goals. For example I have made up my mind to actively seek out new friendships for 2010.
I believe if you want to have successful relationships with others you must first know who you are, define your desires and goals are,and more importantly decide what you want from any relationship you are entering into. Following these principles will not guarantee success but will surely help you along the way.
