If you're not already insane, but would like to be, I highly recommend trying to build a website, as invariably there will be some tiny element that goes awry, some little snippet of code that for no discernable reason doesn't work, and you will spend hours trying to figure out WHY, as you question your intelligence, your eyesight, and the existence of a benevolent and merciful God who would not allow you to suffer like this.
If you're already insane, you'll simply want to shoot yourself in the head for undertaking the project in the first place.
The current status of my sanity lies somewhere in between.
