Confronting and overcoming challenges is an exhilarating experience. It does something to feed the soul and the mind. It makes you more than you were before. It strengthens the mental muscles and enables you to become better prepared for the next challenge.
What you want will pull like a magnet. Here's the other part. What for? Purpose is stronger than object. It's the 'What for?' that's even more powerful than the object. And the more you can describe in detail to stir the emotion and the intellect and the spirit and the soul, then the more powerful the 'what for' is.
