The definition of perfection varies from person to person. To some, perfection may only involve outside beauty, while to others, it may involve personality, experiences, or even accomplishments. When striving to be perfect, keep in mind that, above all else, it is important to make yourself happy. Don't try to be perfect for someone else. To be the perfect girl, pursue the features you believe constitute perfection.
Build your confidence. For example, practice good posture. If you're always slumped over, it seems like you're withdrawn and sluggish. Compliment others around you. All the positive feelings in the room will eventually find their way back to you, since people will want to be around you. Don't be afraid to make eye contact with others around you. Spend some of your time volunteering in the community. You'll not only make new friends, but contribute to a good cause.
