When we want to be helpful to each other, we say things like 'don't bang your head against a brick wall.' That is good advice. But what if your back happens to be up against that wall? What if it seems, to you, as if there is nowhere else you can go and nothing else you can do? There's you. There's the wall. You either stand there forever or you bang something against it, don't you? If all that you feel you can do this, is try once more to do what you have failed to succeed at before... maybe it is worth trying again. 
A particular facial expression can sometimes be seen on the visage of a well-known rock or pop star in the middle of a concert. Their eyes reveal that they would really like to be playing their latest composition but they know how much the audience would far prefer to hear them churn out another of their greatest hits. Don't we all find ourselves feeling a bit like this when we have to do what others want us to do? Maybe you should just be glad, that you at least have an act that goes down well. 
It's impossible, tell the sun to leave the sky, it's just impossible...' So goes the old standard by the classic crooner Perry Como. Why was it popular? People have a strange attraction to the idea of impossibility. It sounds like such a final thing. Emphatic. Inarguable. Impossible! Once we have decided that any task, challenge or project comes under this category, we can dismiss it without further thought. Yet something that you have declared to be impossible, may prove possible after all - in the nicest possible way!
People love league tables. They relish rankings. They cherish charts. Who is ahead? Who is behind? How much will it take to turn those tables? What can we conclude about someone's run of luck and someone else's poor form? We scour such snippets of information as if they were cosmic clues to the nature of destiny itself. Yet some things in life just happen because... well, they just happen!
