It may be best sometimes to fib about yourself here

Because if you're always very factual and stuff, and you do that enough, there might be some who collect and analyse those statements and ergo will know you better than you know yourself.

The greater good, therefore is to mix your statements up, say off the wall things, and also plausible things which are nevertheless false, so that only you will have an idea what, who, how and when you are.
