My site is simply about ritual. Write something, anything, no matter how inane or insipid, then upload it by ten p.m. mountain time. I spend at least thirty minutes a day on my site, rarely more unless I'm going to redesign it.

Once you get in the habit of writing the more likely you are to write. I'm going to assume you're not in the habit of writing so you're getting tired because those muscles aren't developed. Just do it once a day for a week by writing a paragraph. Writing "I HAEV NUTTIGN 2 SAY!!!! FUX0RS U!!!!" or something akin to that doesn't count.
