Rabbit out of a hat

I was looking at my Horoscope the other day and this is what it stated.  

If a stage magician wants to pull a rabbit out of a hat, he (or she) must first get a hat... and a rabbit! The art of creating the illusion may be hard to master (or mistress) but it is still secondary to the acquisition of those two key components. With that in mind, let's look at your ability to produce an impressive result from out of thin air. The real question is not, do you know how to do something? It is, do you have access to the basic resources that might be required if you were to attempt such a feat?

  I found this really good because it can be for any one.. If you replace the word "rabbit" with skills, and the word Hat with the word "passion" you will see that this is a great metaphor, or parable.
