Sleeping is for Quitters

This says everything.

"A man of knowledge is one who has followed truthfully the hardships of learning, a man who has, without rushing or without faltering, gone as far as he can in unraveling the secrets of power and knowledge. To become a man of knowledge one must challenge and defeat his four natural enemies.
When a man starts to learn, he is never clear about his objectives. His purpose is faulty; his intent is vague. He hopes for rewards that will never materialize for he knows nothing of the hardships of learning.
He slowly begins to learn--bit by bit at first, then in big chunks. And his thoughts soon clash. What he learns is never what he pictured, or imagined, and so he begins to be afraid. Learning is never what one expects. Every step of learning is a new task, and the fear the man is experiencing begins to mount mercilessly, unyieldingly. His purpose becomes a battlefield.
And thus he has stumbled upon the first of his natural enemies: fear! A terrible enemy--treacherous, and difficult to overcome. It remains concealed at every turn of the way, prowling, waiting. And if the man, terrified in its presence, runs away, his enemy will have put an end to his quest and he will never learn. He will never become a man of knowledge. He will perhaps be a bully, or a harmless, scared man; at any rate, he will be a defeated man. His first enemy will have put an end to his cravings.
It is not possible for a man to abandon himself to fear for years, then finally conquer it. If he gives in to fear he will never conquer it, because he will shy away from learning and never try again. But if he tries to learn for years in the midst of his fear, he will eventually conquer it because he will never have really abandoned himself to it.
Therefore he must not run away. He must defy his fear, and in spite of it he must take the next step in learning, and the next, and the next. He must be fully afraid, and yet he must not stop. That is the rule! And a moment will come when his first enemy retreats. The man begins to feel sure of himself. His intent becomes stronger. Learning is no longer a terrifying task.
When this joyful moment comes, the man can say without hesitation that he has defeated his first natural enemy. It happens little by little, and yet the fear is vanquished suddenly and fast. Once a man has vanquished fear, he is free from it for the rest of his life because, instead of fear, he has acquired clarity--a clarity of mind which erases fear. By then a man knows his desires; he knows how to satisfy those desires. He can anticipate the new steps of learning and a sharp clarity surrounds everything. The man feels that nothing is concealed."

Procrastination isn't laziness. It's not something to brag about, or even something you can dismiss as trivial. You only delay the inevitable when you are afraid.
