Think of a cook looking....

.....in a pantry.  (Remember them?  You don't?  Oh well Google it.)  Anyway, I digress - The cook concludes that it is impossible to create a particular dish with the ingredients at their disposal. But this is not the only dish that the cook is capable of making. Those ingredients, unsuitable though they may be for one particular recipe, may yet prove the ideal combination for another meal.

It is not enough just to say, 'I haven't got what I need.' You have to ask, 'How can I turn what I've got into something worthwhile?' If it is worthwhile, it will yet turn out to be exactly what is needed.

The ladder of success is best climbed by stepping on the rungs of opportunity.
