A few of these memories will do, I hope you have more than a few, and a lengthy list can give you far more to play with. Don't hesitate to go way back in time. One of my favorites was a time when Chelona and I were courting. It always makes me smile when I remember. Now, there is one caveat I would advise as you begin to practice this new version of Mind Time.
Some people have a very bad habit of turning the positive into a negative.
For instance, in my dinner example some people would then proceed to look at how few times she cooks now and then revert to Stephen Kingish thoughts. What a waste of time and an abuse of yourself and each other. For me, I smile even more because knowing how little she likes to cook, that event grows even bigger and better. A sacrifice by her, for me, just as it is now anytime she cooks for me. So actually, all the meals she cooks become great material for Mind Time.
