This is a principle first discussed by Aristotle. Too much of a good thing can turn into something bad. Virtue can often be found in the middle ground, between two extremes of a characteristic. For example, take self-love. An extreme excess of this principle will result in narcissism, but an extreme deficiency will produce low self-esteem. You need to love and respect yourself to show love and respect to others, but you need to love yourself in moderation so that you do not get carried away. If you really want to be a virtuous woman, you need to prepare yourself for a lifetime commitment. A virtuous life is not an act you can put on for a few days. True virtue is a lifestyle. You can commit yourself to a virtuous life without becoming a perfectly virtuous woman overnight. The best way to create virtue in yourself is to practice virtuous behaviors so often that they become new habits. Do not be discouraged by past mistakes or mistakes you make along the way. Ultimately, if you practice principles of virtue long enough, they will become habits and characteristics of your overall person.

Summary:
Orient yourself to the mean, not the extremes. Commit yourself to a virtuous life. Practice virtue until it becomes habit.
