If I don't feel like writing, I don't. I would prefer not to write than to write garbage. Maybe your brain is telling you you need a break. I wouldn't refuse it that right. If it's something you're forced to write, then sit down at your computer and make the surroundings as comfortable and homey as possible. Play some music you think will aide that. Ergonomics play a key role, as well. Little things mean a lot. If after all these have been attempted and still the words won't come, walk away (metaphorically) and read over what you've written. Maybe you hate it and just can't get up the courage to admit it to yourself. Been there, done that... and it works every time.
