Seems like I will never find the one for me?

I'm 23 years old and I am frustrated with dating! I am always seems to be the girl who just meets the wrong guy at the wrong time. I am a very nice, easy going, attractive, and successful girl. I'm not conceited, controlling, or stuck up. I am simple, easy going, and just like to have a good time. For some reason I just can't find anyone and I'm getting discouraged. I haven't been out searching and looking for someone, I've just tried to enjoy being single and let things happen how they will. But I'm beginning to get discouraged and lonely. Advice, encouragement, and similar stories would be very much appreciated!
