They said to write a list. Your wants and dreams, whatever you're looking for. Somehow it needs to exist in the physical realm, so you put it on paper like a letter to the universe.
That's the whole trick, to define it. "What I really want." And then wait patiently, with your eyes open, so you recognize it when it finally comes. Maybe this step takes a long time. The universe has it's ways.
But when it comes, that thing you wanted, you're ready. And it's amazing. You want to write the universe a thank-you note. You take a picture of yourself a dirty mirror instead, like a memento in case you ever forget.
"Yes, I can be happy. I never thought I would, but I am. Please remember. It happened. I don't care if it doesn't last, the important thing is it exists. This is what it looks like." *click*
