Experince versus knowledge

Hey. So I have a question and I really want your advice. But In life (in particular in love because thats what Im most interested in) do you think you HAVE to have experince or negative experience to teach you what you really want or dont want? Do you think its possible for people to know what they want without experince personal experince? Is knowledge and searching within yourself enough to know what you want really out of love and life at least in certain aspects? Please provide your examples and your experiences. Thank you all.
