A psychology teacher walked around her class holding a half empty glass of water. The students were all waiting on the ‘half empty half full glass’ question. Instead the teacher asked “How heavy is this glass?” “8oz, 12oz” the replies came. In fact the actual weight of the glass doesn’t matter. How long I hold it is more important. If I hold the glass like this for five minutes there isn’t a problem. If I hold it for an hour my arm might start to ache. If I stand here and hold it for a day my arm might become numb and paralysed. But in each case the weight of the glass stays the same, but the longer I hold it the heavier it becomes.
Sometimes you have to remember to put the glass down.
