This may sound basic but it is important to think about some searching questions, find out what you really like and don't like, consider what has helped you in past relationships and what has not, exactly what do you find attractive, what personality types you bond with etc. This could sometime be a little emotional but it's important to be truthful with yourself. A buddy can also help with an external viewpoint on a few of these questions.

Once you have finished your own personal profile, gradually alter build up a profile of the type of partner/friend/lover you are interested in looking for.
