Preparation, what does it mean. Be prepared is to know. For example, you have a job interview. You know what kind of question are on the interview, but you have never thought about them. When you are asked a certain question and your not ready to answer, that means that you are not prepared. When You take a test, for anything. You have to be prepared for the test. You have to know the subject. Preparing your self for the worst will bring you success in what ever you do. Have you heard about a saying... "Somebody did not do their homework". It a same thing, the person were not prepared. That means that the person has failed the subject, or an interview or what ever. Do you homework and know everything about your task. Make it fun to learn, so you remember everything.
"Hope for the best, be prepared for the worst".
