Being patient

Being patient is so hard.  I really want my case worker to get back to me about the questions I had so that I can send our application in.  I know that he said he would not be able to answer them on Tuesday but it is now Thursday.  What's the deal!  It is so hard to know that you are being let somewhere but that the process is dependent about SO many others who don't share your unique enthusiasm about the opportunity.  How do others deal with this?  It is hard to think that we have just begun and that there is only 1 1/2 to 2 years more ahead of us!
