I would listen to NONE of that advice!!! I can understand if you are interested in finding the "right person" for you, but first, find out what you want. Not just in a relationship, but other things as well. Do you really want to try sky diving or take art classes? Don't put off doing what interests you and will help you grow as a person. Learn to enjoy the little things. If you are well adjusted, happy and in tune with your own wants and needs you have a much better chance at choosing the right type of person to be with.
Not only that, but if you are happy and self-confident you will be attractive and appealing to others as well.
