While you obviously want to look your best and market yourself well, you don't want to make your potential matches feel duped the first time you meet them. Keep your photos recent, fun, and showing your favorite hobbies to give a visual glimpse into your life, and you will do well. Say what you aren't looking for: While this can come across as negative to some people, you aren't online to please everyone; you're after the right match, for you.
