Try to keep your design fairly compartmentalized, and loosely coupled. That way, when you do find a flaw in your first design, you don't have to throw everything away: some of the code you've already written will easily work with your new code. (For instance, if you're always updating a database the same way, and you keep the database update code well-separated from everything else, you won't need to make any changes to it when you realize that your interface code is hopelessly screwed, trash it, and start over.)
