You can be secure, sweet, and humble all at the same time. But be prepared to come out of your shell. Guys like confident, interesting girls who lead their own lives. The only guys who like insecure girls are the ones who are insecure themselves and want to dominate another human being. And who wants to be with a guy who wants a girl to feel bad about herself or who wants to tell you how to be all the time? That's not healthy, and you deserve much better. A little make-up can go a long way. You don't need to color-by-number your face, but mascara opens up your eyes, lip-balm enhances your smile, concealer can cover any small insecurities, and tweezers could really help nightmare eyebrows. Just wear what you are comfortable with. Dress in clothes you feel comfortable in. Don't squeeze yourself into a body-con skirt if that's not your usual style. A well-fitting pair of jeans and a top that brings out the color of your eyes is a safe but striking combo. Smile a lot and research to found that people become more attractive to others when they smile, so flash those pearly whites as often as possible to look prettier, as well as friendlier and more approachable. Most guys won't ask you out because they're afraid of getting shot down. You've got to walk before you run, right? Say "Hi". Say "Goodbye". Give a little wave. When he reciprocates, you'll know that you have his attention. Introduce yourself somehow and make conversation. It's nearly impossible for someone to like you if he doesn't get to know you unless he "likes" you for all the wrong reasons.
