There are two issues, I think.
- how much you write (wordcount)I've tried writing every day. But I started to go a bit strange. Considering I was quite strange to begin with, I had to be careful about this. These days I write five days and take two days off. Writing every day of the week tends to send me mad.
- how often you write
If you have a deadline, however, you may feel differently. You might want to write every day and all night until your editor stops hitting you with a big stick.
