take A LOT of pictures... NEVER compare yourself... And tell yourself "you can" instead of "you cant" Always think of things going great i stead of horribly and be yourself... If you want this to happen, get your friends to help! They will do anything for you trust me! Ask them what they like about you... But tell them why you are asking! Friends AND MOMS always help with these kind of things
You can stop being shy by starting to be more social. This can be done by spending more time with friends and family and do some activities that you enjoy. The more time you spend with friends, the sooner you will feel comfortable round people.
