Use every Mary-Sue possible!
Be cliched; you know we all love that~
Don't use a Spell Check before uploading. Ever.
No research if you're using a foreign setting. Readers can't tell the difference these days.
Get pissed off when helpful critique is offered to you.
Use LOTS of sentence fragments and run on sentences.

In addition:
1, Never use ordinary names; they're boring and they don't tell the reader anything about the character. You should always name your characters after their physical and/or personality traits.
2, Always type one huge paragraph; anyone who says you shouldn't do this is just being a grammar Nazi.
3, Whatever you do, don't touch the Shift key. You must either type in all caps, in which case you should use the Caps Lock, or not bother with capitals at all.
4, Regarding your "no research if you're using a foreign setting" point, this should be "no research - period". Research only bogs you down with details and gets in the way of the plot.
5, If writing fanfiction, remember that your interpretation of the series concerned is always 100% right and anyone who disagrees is not a "true fan".
