When the fire alarm goes off in your school you have a fire escape
      exit that is the first, or "preferred" choice for the classroom
      in which you happen to be at the moment. It is usually the exit that is
      the closest and most convenient for leaving the building. 
       You also have an
      "alternate" exit just in case the first exit is blocked.
      It is important that you know where both exits are
      located. 
       It is also important that you know how to get to the
      "alternate" exit from the location of your primary or
      "preferred" exit. Because if you ever find yourself in a life
      and death situation and your first exit is blocked, you won’t have time
      to waste. You will have to proceed quickly and directly to the alternate
      exit in order to escape the danger. 
       Admittedly, the chances of both exits
      being blocked at the same time are slim since your alternate exit is
      usually in a much different location in the building. This too is
      important, for if your alternate exit happens to be blocked, you are in
      very serious trouble since you seldom have a second alternate exit.
      And so it is with your post-secondary education path. 
      
      If the preferred path to a satisfactory career (comparable to the
      preferred fire escape exit at your school) doesn’t work, then you will
      be forced to take another alternate path (comparable to the alternate fire
      escape exit). You should know what that path is before you have to use it,
      because if you fail to find satisfaction the first time around, you will
      likely be in a desperate state of mind and blindly try to find your way
      out of a bad situation.
      As we go through the next section you will begin to understand why the
      private career colleges have become the "preferred option" when your first "preferred path" doesn’t give you
      the desired outcome you were looking for.
