Confidence makes a huge difference. If you believe in yourself it's more likely for you to fulfill your dreams. It is important to love yourself the way you are. It's a cliché, but how can anyone else love you if you don't even love yourself. I sometimes remind myself of that. People don't want to be friends with a cranky person who can only find flaws in herself. So get out there, shine and be yourself! Don't let anyone get in your way. Be strong. Don't crave people who don't deserve you. Don't get dependable on any person who doesn't care about you.
Don't be afraid to make a fool of yourself. Go for it, let go. Don't care what other people think about you. They rarely do. But even if they do, who cares? It's just that person's opinion.
