Running in circles

I was chatting with the hubby this morning about how much there is to do between now and the end of the year. Then we talked about how busy June will be. July and August shouldn't be too bad. Then we talked about how school will start again and then we have this and this and that and this and all of a sudden it is next summer! How does this happen? I don't even consider us busy people. Does it ever slow down?
