A word of encouragement: There is light at the end of the tunnel, so do not give up! I guess, if one were to take a poll, or do some kind of extensive research, probably it would reveal that there are several thousands or maybe even millions of people who have and are doing just as the title says, "building castles made of sand." As I look back over the past few years, I find that this is exactly what I have done too. I am sure, that there are many times when you are ready to throw in the tow.
