Habits, regardless of size or nature, can be exceptionally difficult to
break. This will take a lot of effort but you can do it. Unfortunately,
poor habits can be the one aspect of your behavior that could be the
obstacle to your success. If you have a habit of sniffling or chewing
your nails when you get nervous or saying demeaning or offensive
things as a way of trying to control, to be successful, whether on a
personal or business level, you have to stop.
