I try to write every day. I used to try to write four times a day, minimum of three sentences each time. It doesn’t sound like much but it’s kinda like the hare and the tortoise. If you try that several times a day you’re going to do more than three sentences, one of them is going to catch on. You’re going to say “Oh boy!” and then you just write. You fill up the page and the next page. But you have a certain minimum so that at the end of the day, you can say “Hey I wrote four times today, three sentences, a dozen sentences. Each sentence is maybe twenty word long. That’s 240 words which is a page of copy, so at least I didn’t goof off completely today. I got a page for my efforts and tomorrow it might be easier because I’ve moved as far as I have”.
