No matter how busy a man is, he will always make out time to eat. Because he knows what will happen if he does not. He knows he must attend to his stomach on a regular basis. Likewise, our mind eats too. But apparently, a vast majority starve thier minds to death, hence not making them make any mark on earth. If you can create time to feed your stomach, you should deliberately chisel out time to feed your mind with relevant information through books. A word is enough for the wise.
