Blog frequently and candidly. The words are in there, let them flow. Don't lose the moment to overdigestion of thought -- let the moment flow.
Be effortless and don't spend eternity on each post: just blog. It's more like a small late night gig than an epic big-budget masterpiece: it should only be so perfect. Imperfect is good.
Don't lose yourself to the nonexistent person you think the world should see and admire through your masterful posts. Post frequently and you won't lose your day-to-day human charm and flippancy to some imaginary work of a genius you feel you owe the world with each post. Remember, when you're trying to be too perfect you're not blogging.
Don't become your blog -- just blog.
