There’s a metaphor in the idea of finding a four-leaf clover. It represents good luck, but to find one, on average, you’ve got to spend a lot of time and pay a lot of attention. So the principle of putting in hard work to get “lucky” is part of the deal.
There is, too, a metaphor in buying a framed four-leaf clover and having it delivered to your house instead of looking for one.
