The uncertainty principle

So much of the tension in our lives arises from uncertainty -- and our efforts to control it.  Will I make this hurdle?  Will I win the race? Will it make a difference in how people treat me?

As the uncertainty escalates -- will I be able to make the rent this month? Is it a tumor? Will he survive the operation? -- tension escalates right along with it, and so do our efforts at control.

But isn't it also true that without uncertainty life would seem incredibly stagnant and boring?  Isn't uncertainty also the source of a great deal of creativity?  Somehow we need to strike a creative balance between uncertainty and control...
