Juulie - I used to work with a guy who had the following theory about how to succeed in life. He said that you needed to understand just three principles. They are:
1) Don't make a promise you can't keep unless you are a damn good liar.
2) You can get anyone to do what you want, as long as you can trick them into thinking it's good for them.
3) Women are looney.
I think he's right on two of them.
