" We need the courage to START and CONTINUE what we should do, and the courage to STOP what we shouldn't do." 

--Richard L. Evans--

  What this is saying is that if your doing something good the you need to have the courage to continue doing good because it is the right thing to do. If you aren't doing no good you need the courage to stop doing that because that isn't the right thing to do. If you aren't doing anything either good or bad you should start doing good and then continue to keep doing good. For example lets say you always get left with a lot of homework but you procrastinate in doing it and you wait until the day before everything is do or like before you go to sleep that is bad and you should stop doing it, or lets say you always have the habit of studying the day before you have test or quiz that is bad because you don't get any rest and you'll probably forget what you studied for the test. lets say you leave your studying for the day of the test and you try to remember as much as you can before taking the test but you can't because you didn't have enough time to study so therefore you fail the test and don't pass the class. Therefore you need the courage to stop what you shouldn't do and the courage to start and continue what you should do, what is the best for you.
