Patience

Have you ever spent an hour on the phone with a company to get something resolved?  Ok so the call may not pan out how you wanted, but patience is always key.  Yes it is easy to get angry with the person at the end of the phone, but chances are they are not specifically responsible for the dilemma or problem you are facing.  Being rude and shouting at someone else only creates bad feeling on both sides, and who wants to ruin their day by being unkind to someone else?  Patience and perseverance will see you through and you will be a better and probably happier person for it in the long run.  That is not to say that you are grovelling to them, you can still be forceful and polite to make a point without behaving in a way that is offensive and rude.  If you are going through a hard time getting something sorted just remember the number of hours in the day and remember that most of your time will actually be spent doing other things.  It kind of put things into perspective if you look at it that way.  Don't worry, you'll get things sorted in the end.  Sometimes it just takes longer than you anticipated.
