If you haven't worked with morning pages before, think of it as writing whatever pops into your head -- you're writing about anything at all that pops into your mind.
You're not writing to be read by anyone, not even yourself. You're clearing your mind of all the junk that's in there. Write your pages first thing in the morning, as soon as you wake up. (You may need to get up half an hour earlier than you usually do.) Just write whatever comes.
"Whatever comes" might be truly horrible. I remember that when I first started writing morning pages over a decade ago, I spent at least six weeks whining on paper. Finally I got bored listening to myself, and looking back, I think that's the key.
When you dump everything onto paper, you can finally see yourself, and hear yourself -- and you'll get tired of all your problems and concerns. It's as though you're spring cleaning your mind.
I'm excited about doing morning pages again; I'll let you know how it goes. :-)
