Balancing Act

Maybe it's just me, but the busier I get, the more productive I get (and better mood I am in).  The problem I have is finding the balancing point where I am running at maximum levels but not to a burn out level.  Seems like I often lose sight of where I am at (and what is coming down the road) and  fall on one side or the other.  This situation then creates a boredom to burn out and back again.  Oh well, who ever said salespeople were easy to understand...
