Most people will have had experience of a task that was left undone until it reached crisis level. The trouble is that then it usually demands to be done when the point of greatest inconvenience has been reached. Either the weather is poor, the days too short, or cashflow at a low ebb and then we wish we had done something sooner.

If something needs to be done, the likelihood is that the situation will never improve and the cost of repair will almost always spiral well beyond the cost of early maintenance.
