Second, the initial stages of learning a skill invariably involve tedium. Yet rather than avoiding this inevitable tedium, you must accept and embrace it. The pain and boredom we experience in the initial stages of learning a skill toughens our minds, much like physical exercise. Too many people believe that everything must be pleasurable in life, which makes them constantly search for distractions and short-circuit the learning process. The pain is a kind of challenge your mind presents - will you learn how to focus and move past the boredom, or like a child will you succumb to the need for immediate pleasure and distraction? Much as with physical exercise, you can even get a kind of perverse pleasure out of this pain, knowing the benefits it will bring you. In any event, you must meet any boredom head-on and not try to avoid or repress it. Throughout you life you will encounter tedious situations, and you must cultivate the ability to handle them with discipline.
