I threw my copy of 'the rules' out at uni as it was doing my head in; it was so pescriptive but as I am still single and have a tendancy to chase men I thought I'd give it another chance.
Some of it I agree with such as :
" It dosn't matter if you're not a beauty queen, that you never finished college, or that you don't keep up with current events. You still thinkyou're enough!"
Some ideas are awful such as:
"If you have a bad nose get a nose job." 
Also surely this advice is contradictory. If it dosn't matter if we are not a beauty queen why go to extreme measures to get surgery to attract a man?
I mean was this book actually written by a man?!
But what about all the playing hard to get stuff? I guess there might be something in that?
