The value of an item will be known when it is not availableEvery item will have its importance in our lives. But we will not know the value of the same when we have plenty of it. We will feel the importance only when it is not available. This is very common.
When we perform parties and functions, we will plan well in advance all the items and arrange them so that at the last minute we need not run here and there for that item. It may be a very small item but without that, the whole program may not move.
Even in manufacturing industries by any chance if any raw material or any other essential item is missing, the whole activity will come to a standstill. The cost of the item may not be very high but the absence of the same may make us lose heavily in production
Even in our daily life if we want to eat any item we will order from outside and eat it. But since the last year, we are not eating any outside food. We can't make everything in the house. This is making us feel that we are missing something.
On normal days we never think of Oxygen. But now everybody is talking about this item and people are able to understand the value of air that is freely available to us.
As such I say the value of a particular item will be known when it is not available. I think other members will also accept the same.
