The great thing about writing every day is that, if you persevere with it, and if you have a good attitude and relationship with the writing process, it can become a habit that borders on addiction. It's a constant challenge, but it's also consuming, distracting and pleasurable.
We all have something to say. When we get in the habit of putting it on paper, it begins to feel as if we are being heard--or at least that we might be heard. Putting it on paper can have all the gratification of imagining that snappy response an hour after the conversation took place. "Ah, but I should have said that! That would have shown how brilliant I am!"
Sure, tomorrow we may hate what we wrote, but in the moment, in that brief moment when you feel that your words are perfect and precise, is that not a moment of intense emotional gratification? And the more we practice our writing, the more common do we experience at least the sense that we are on the verge.
Once you begin, and one you give yourself to the project, it can become addictive, so that you end up returning to it, despite the pain and frustration you might have felt. Sometimes, anyway.
Ok, sure, it's easy to lose the habit of writing. Writing is difficult. But it's compelling, too. The sense of loss when you give it up can be significant.
