1) Make new friends. This will help you through life; friends will help you through life. And who knows. You guys may end up being best friends for life. This will give you the courage to go up to anybody who you like and just say hello.
2) Be daring. Maybe there's one more spot for the talent show or you might be in Drama and you want to get a lead role but you're too afraid to admit it. Don't be scared. Be proud of who you are and don't worry of showing off. Don't be a big snob, but hopefully you get the whole idea.
3) Love yourself. This is key to building self confidence. I want you to wake up and say three things about you, a family member, and a friend.
Hope you found these tips helpful. Bye1
