With desire being so important to achieving goal, I found interesting blog post on highexistence.com which share a Zen Buddhist Fable that really helps highlight a different perspective on the levels of desire required to focus on what you want.
A man approaches a Zen Master and asks to be shown the path to enlightenment. The Master replies, “Okay, follow me,” stands up, and walks the man to a nearby river and into the water. Without warning, the Master forces the man’s head under the water and holds it there as he struggles violently for his life, until he is nearly dead. At last the Master pulls the man up, gasping for air, and says, “When you want to be enlightened as badly as you wanted to take your next breath just now, come back and see me.
You just have to want your recovery, performance, and pain reduction as much as you want air, or just really want it so much that is becomes your focus.
The blog then highlights Napolean Hills quote
When your desires are strong enough, you will appear to possess superhuman powers to achieve.
Desire, Desire, Desire is the starting point leading on to expectation and belief then you achieving your goal
Desire is the starting point of all achievement. Not a hope, not a wish, but a keen, pulsating desire which transcends everything
