People

What sort of relationships do you have with people? There are many forms ranging from formal contractual arrangements (contracts to do something... buy a house) to informal consensual contracts (meet up for a drink... sometime)
 
Either way is the flow of the relationship unambiguous? i.e does each party know what is going on?
 
Misunderstandings (and World Wars) arise from insufficent anlaysis of the type of contract/relationship that is being formed.
 
Similarly, be clear and direct what you want out people so that your wishes and desires are clearly communicated.
Understand what the other party is getting out of the arrangement and listen to the other person and respond when there is a mismatch in relationship perceptions.
 
Pick the right 'contract' that is appropriate for the relationship, whether it is formal and there are strict guidelines and timeframes, or informal where rules equally apply (turn up at the right place at the right time for that drink) .
 
Consideration of the other person's point of view is more easliy attained when there are some guidelines in place no matter how formal the relationship.
