Morning Pages
Keep a notebook and pen by the bed. Within five minutes of waking, before coffee, before your phone, sit up and start writing.
Write whatever comes. Complaints, plans, fragments, embarrassments, lists, grievances, joys. Don't edit. Don't worry about grammar. Don't stop to think about whether something is worth writing.
Target three full pages. Some mornings you'll fly through them. Other mornings you'll strain to fill one. Both are fine.
When done, close the notebook. Don't reread. Don't show anyone.
Morning pages clear the stream. The stuff that would otherwise rattle around your head all day gets externalized in 20 minutes. You don't need to act on any of it. You just needed to see it. After a month of daily pages, most people report measurably less mental chatter and more clarity on what actually matters.
