One approach is to go through the specification of the program,
underline all of the significant nouns and try to implement each of
the nouns as a class. That won't take you all the way to a good design
-- some of the resulting classes will be too trivial, and it won't
give you the derived classes you need, but it's a good first step to
breaking a problem down, and might help break your one big class
habit.
