Computing pioneers soon learned how to speed up the transmission of images from one machine to another. Rather than send a description, pixel by pixel, they would analyse it first. Where one tiny section looked much like another, they would send a code that said, 'same as the last one.' There is a similarity here to the way in which we receive information from our own senses. Mainly, we form general impressions and focus only on differences. Take care now not to blur the edges of an assessment that warrants far greater scrutiny. 
In emotional and business relationships alike, people sometimes accuse others of 'moving the goalposts.' How strange that we should employ this idiom, even when we are not engaged in sport. And, in a world of infinite possibility, why shouldn't someone invent an entirely legitimate game in which the strategic, deceptive movement of imaginary goalposts is a key component? Who says that all rules must be forever fixed? The fluidity within your current situation may be irritating, but it can yet be beneficial to you.
 At many a live pop concert around the world, a time-honoured ritual takes place, whereby the vocalist sings a musical phrase and invites everyone in the audience to sing it back to them. This quasi-theatrical device is known, in the entertainment industry as, 'call and response'. It provides great fun for all concerned. Life makes calls upon us all and often our responses are neither smart nor spontaneous. We just do what we imagine is expected of us. But there may be a much better answer to today's question.
 Have you ever met a person who really knows exactly what they are doing? Perhaps, in some limited field of engagement or endeavour, it may be fair to declare them an expert. But expertise is never synonymous with infallibility. We all make mistakes. We all get out of our depth. And the worst of it is, we can't always be entirely sure when this is happening to us. Why worry about whether the choice you are making now is appropriate? You have done your best to reach a clever conclusion. Now you must trust yourself.
