Just in case any of you don't know, NaNoWriMo stands for National Novel Writing Month, which is November.
It is a month when all authors come together to create a novel in a month; but of course there are tricks to getting there faster.
One ; Patience and persistence. Never give up. If you do, you'll never be able to finish your story, thus concluding in self-acclaimed writer's block, which is only caused by your state of mind.
Two ; A good plot and good characters! If you bore yourself, you bore your readers. You could print out a workbook which the site [http://ywp.nanowrimo.org] offers for free.
Three ; Leave the fun/boring part for the last. Whatever it means to you. When you're writing, just WRITE. Don't mind the spelling and grammar errors, just WRITE. If you revise as you write, it'll be a long time til you finish your chapter.
I learnt that from experience, mind you. I gave up, I had a boring plot, and I revised as I wrote. How bad am I? xD.
Please, remember 2011's NaNoWriMo and have fun!
