There are many writers who are able to diligently button down (as in "butt-on-chair" down) and hit that daily word limit they set for themselves. Others (who shall remain nameless but might be me) need more of a challenge to push them to reach that goal. Challenges could include working with a reading/critique group or signing up for a challenge that encourages accountability (such as NANOWRIMO--a novel in a month?! Sign me up!). And for others still, that word count is an elusive specter to be chased but never quite caught. So maybe you just give up. Surf the internet for a while. Teach yourself to crochet.
