Love is like a mountain,
      hard to climb,
but once you get to the top
   the view is beautiful.................We always want our guarantees to be cast iron. We don't want to place too much weight on a platform that may collapse. We feel that there is strength in certainty - and so there is, up to a point. Beyond that point, though, lies a realm where the unexpected reigns supreme. We must legislate for its existence, even though we know that we are unlikely to stray into it.
The definition of insanity is doing the same thing over and over again in the hope that it will bring a different result! Perhaps so, but that's also the definition of optimism. We have to have faith or we really will go crazy. Sometimes we have to keep repeating an exercise and hoping for the best. And sometimes there's no option, other than to shrug your shoulders and give up. That's not something you can do now, and nor should you. 
Focus on your life
