I am so glad I found this site, I hope it will help!
While you take that walk, look around at the scenery, its beauty, the clouds if there are any, feel the weather on your skin, it's real air, fresh air. Think good thoughts, continually repeat a mantra and when your mind goes back to it, when you realize it, just return back to the mantra.
And since you don't know where to start - go to lesson 1 and follow it, I have the sheets at my office and at home (you'll understand when you read about the lesson). Everyone does it at their own pace, I do one a week, and practice the lesson thru the week.
Read the posts, not just the current ones, go back and see what strikes your fancy. And keep posting.
Let us know of your success with your walk. I have faith that you will enjoy yourself and jump for joy when you return home. And if it goes a differnt way, that's okay, too. Opeing the door and looking around is just as special.
