I think writers of memoirs need to be respected for the bold decision they take to bare their lives open. That alone should be enough. The things I write about, if you notice, are sensitive issues for a lot of people. If I told you my age, they would get ideas. The next thing you know they'll be filing lawsuits against me.
For the last few years I've tried to force myself to write at least one page every day, which doesn't sound like much but it's actually pretty hard to manage. Because I'm not allowed to do a make-up day. I can't do two pages the next day. The punishment for not completing my page is that I have to eat a vegetarian meal the next day.
