Parable about desire

One day a man came to Master and asked him to teach him how to succeed in life. The sage made him climb into a barrel of water and plunge into his head. Then, with all his strength, he held his head so that he could not get up. Finally, with great effort, he got up, overcoming resistance, and sighed.
"What did you want when you overcame my resistance?" The sage asked.
'Breathe,' answered the student.
- And what else?
- Nothing else.
- This is the power of a single desire. You can so want success, you can achieve it.
