On motivation

So two weeks ago when I decided to start posting daily, I figured it would make me think and come up with something creative to say every day. I'd get the feeling of accomplishment of doing something worthwhile, along with the catharsis of self-expression. Yeah right. I should have known that I would put it off until late each night, giving me a few minutes to hastily cobble together something that passed for a post. That's not an accomplishment. That's not interesting to read or write. So I'm back where I started. I need to blog more, but it needs to be meaningful blogging. Making it a daily task makes it feel like a chore that I must do, but if it's not scheduled, I don't do it. Ideas?
