The study of Scripture I find to be quite like mastering an instrument. No one is so good that they cannot get any better; no one knows so much that they can know no more. A professional can spot an amateur or a lack of practice or experience a mile away. His technicality, his spiritual ear is razor-sharp. He is familiar with the common mistakes, the counter-arguments; and insofar as this, he can clearly distinguish the difference between honest critics of the Faith and mere fools who criticize that which they know nothing.
Think Easy, Light, Smooth, and Fast. You start with easy, because if that's all you get, that's not so bad. Then work on light. Make it efforthless, like you don't give a shit how high the hill is or how far you've got to go. When you've practiced that so long, that you forget you're practicing, you work on making it smooooooth. You won't have to worry about the last one - you get those three, and you'll be fast.
