Throw a barbecue or party in which guests bring a friend that no one in the group knows.
Sometimes it feels like the foundation of your social life is so strong that you no longer find the opportunity to meet new and exciting people.
Put in writing what type of relationship you hope to find -- both short term and long term. Be committed to spending time daily looking for potential dates, whether online or in the real world.
I recommend setting aside at least 15 minutes each day.
Be persistent and consistent by having a plan in place for meeting quality men. If they aren't a romantic interest, consider making them your friend.
