Pleasure comes from filling a need. A person is in a state of deficiency most of his life and focuses on obtaining that which he is lacking. At times, great obstacles prevent a person from meeting those needs. The more obstacles that arise, the more a person feels the void of what he is missing.

Eventually, when that need is met, the pleasure of obtaining is in proportion to the difficulty he previously experienced. When you obtain what you want without running up against obstacles, your pleasure is limited.
