To get an A in an exam is as redundant as your "first step"
Why are you bothering with the material at all?
That's your purpose.
Without getting clear on your purpose you'll wind up procastinating, because you have no motivation to learn. Your mind will ask, what's the point of all this? If you have no point why do it?
What is your reason for studying? That's your goal and your purposeful steps along the way are merely actions you are taking to reach your goals. Knowing why you are doing it is your motivator.
