Has this ever happened to you? You decide you want a lazy evening on the couch watching a movie on Netflix. You already have a particular movie or narrow genre in mind. You scroll through the thousands of offerings, but not one of them sparks your interest. Maybe you give up and surf the net instead.
I see many people approach dating the same way. They decide what they are looking for and then cull the options that do not fit the specified criteria. Be open to new genres; you may find yourself surprised at what you like.
