Women can be turned on in an instant by a winning smile or sense of humor, but they can just as instantly be turned off by a few horrid habits and traits. A couple of the traits are easy to fix by simply paying more attention to your hygiene. Others, however, may take a change of heart and practice on your part. The practice might not make you perfect, but at least it could make you tolerable. That is, of course, unless you thoroughly enjoy being single, repulsive and alone.
