Steve Pavlina, in an article called Feeling Blessed:
Once you’re feeling relieved and comforted, even if you’ve had to drug yourself with food, wine, and mindless entertainment to reach this point, you’re in a reasonably good place to start thinking about what you want instead of what you don’t want.
Don’t worry about action just yet. That will come later. Just start thinking about what you want. Dwell on it. Obsess over it. Imagine how you want things to be. Imagine everything in your life working out beautifully.
Don’t worry about practicality. Just fantasize. But fantasize in a specific way. Sit on your couch (or a chair or park bench if people came and took your couch away), and imagine that what you want is actually becoming real. Put yourself in the frame of mind that it’s already happening.
If it takes you 10 or more minutes just to get a clear picture of some small part of your life getting better, then so be it. Put in the time. Deliberately thinking about what you want is a very important activity. This kind of visualization is an outstanding use of your time.
