What are you looking for?
Write a list of all the things you are looking for in a man. For example, tall, dark, handsome, rich, old/young. Now cut the list up. For example, looking for tall, handsome rich guy in his mid 20`s. Personals usually only allow so many words so it is important that you put the most important things that you are looking for in a guy instead of silly trivia bits such as, must have blonde hair, blue eyes etc..

Who are you?
Now do the same but write a list that you think best describes you. (Honesty is the best policy.) How old are you? Are you thin, petite, big built? Are you tall/short etc.. Now narrow the list to a small description of yourself.

Your interests
What do you like to do? Have you got an amazing hobby? People that read personal ads are looking for a potential partner so they will want to know if you have anything in common with them. Again write a short list of the things that you are interested in. Don`t just write that you like quiet nights in and out so does everyone. Make it clear exactly what you like such as, ice skating, art (write the name of your favourite artist.) Concentrate on what you like that way you will attract guys that are interested in the same things as you.

Make your ad stand out
Most personal ads look and sound the same. Why not make your ad stand out from others. Write you ad in the form of a poem. Add some humour. Use song lyrics. There are many ways in which you can make your ad stand out you just have to ad a bit of imagination.

Honesty is the best policy
The most important thing when describing yourself is honesty.  You are who you are and will only attract a man who wants the person you have described. Which means you will lose out.
