When I first started doing gymnastics I couldn’t do very much but after I did a basic course in Scientology I started getting better, and in about a month after the course I was on the gymnastics team at my gym. That year I was competing and doing well.  You see, understanding about something opens the door to being able to do the correct actions on what you study, and without this, you can never be a professional.  Try reading something where you do not know the meaning of half of the words you are reading, and then try doing what is described in it.  You probably would do something different than what it tells you there to do.  Then, grab a dictionary and look up all the words that you cannot define and you will see what difference it makes.
