Gordon,
I found this explanation visiting a Buddhist Thai Temple site (http://www.buddhapadipa.org/dhamma-corner/no-shortcut/)
No ShortcutWe human beings don’t want to go to any trouble. When we want something, we like to have it without making an effort. It is impossible to have things without making an effort as we know from life. What we want can only be gained through a lot of effort. There is no shortcut for getting things. There is a story told by Ajahn Jayasaro which provides a good example of this. Here is the story:
There was a man who was hungry. When he walked past a bread shop, he bought a bread roll and ate it. The first roll did not satisfy his hunger, so he had to buy a second one. The second one did not fill him up either, so he had to buy a third, a fourth, a fifth, and a sixth. But he was still hungry, so he bought a seventh one, and then the seventh one took away his hunger. He said to himself, "If I had known that the seventh bread roll would have filled me up, I would have bought it and eaten it first!"
