““This morning, my son asked me for money to buy a sheep. Should I help him, do you think?” “Since it clearly isn’t a matter of urgency, wait another week before giving him your answer.” “But I have the means to help him now. What difference will a week make?” “A very great difference indeed. Experience has taught me that people only give value to a thing if they have, at some point, been un-certain as to whether or not they’ll get it.””
