I really like the discipline of writing every day. I am a procrastinator by nature, so I often have something in mind I want to write about but don't get to it before the end of the day. I think, oh, I'll write it tomorrow instead. Then another day comes and goes. Then I have something else I want to write about, but I feel like I can't write about it until I've written about the first thing. So then I go weeks without writing at all.
I have the same problem with other things too. That's why it's no good for me to do something 3 days a week, or 5 days a week, or need to make a phone call "sometime this week" because it always gets pushed off because "I still have 5 more days" to get it done. Then all of a sudden it's the end of the week and either I'm scrambling or it just doesn't happen.
In addition to not getting things done, trying to do something irregularly makes me more anxious. I get worked about what I should be doing first, or about not getting to something that's been on my list. It starts becoming an emotional burden. But having a daily discipline takes all that away. I don't have to decide whether to do it today or wait until tomorrow (which so often becomes next week, next month or never!) I know that before the end of the day, I will sit down and write something. Despite the fact that I'm writing more than I have in a long time - or rather, because of it - my list of things I want to write about just keeps getting longer.
