Focus on the positives
I read through hundreds of online profiles every week and it always surprises me when women - and it does seem to be exclusively women - give a list of what they don't want in a man......
Not too small, not interested in anyone who doesn't have a college degree, no children please. Don't want someone with baggage. etc.
What does this say to prospective men when they read it? Lets assume that they are of average height, have a college degree, no children and no baggage - they fit the bill - excellent - do you think they are going to send a message to this woman though? I'd be very surprised if they do.
Starting off with negatives and a shopping list of what you are not looking for in a man is just a huge turn off - and I think you've got to be prepared to give people a chance and not judge them based on a criteria which you deem to be vital in the opposite sex. Broaden your horizons and be prepared to at least message back and forth with a wide range of people - you've nothing to lose and you could end up with someone who holds none of your criteria but all of the magic you require.
