Distractions Abound

Why is it that life sends us distractions at the time when we can least afford the time to follow them?  I never have understood this.  I go along good, time starts running thin, and then POW -- things start happening all over the place that leave me where I don't know where to turn or how to get through things..... Not that these are bad distractions -- in fact, they are not.  The distractions I am facing are quite lovely.  But that does not change the fact that the bar is looming, actually three weeks from today.......
