Worrying is nonproductive and causes problems as well. Couple of summers ago, I was walking on a path through my woods. I had recently got a cell phone and had it with me. I starting worrying, thinking about falling down even though the path was clear. I tripped over my own feet and couldn't get back up. The cell phone worked and I called my daughter. She answered and I told her that I fell down and couldn't get up. She came out on our ranger and helped get me up. Even today, if I don't focus on what I am doing, I find myself starting to worry about things happening to me: falling down the stairs, falling up the stairs -- you can fall going up and well as down -- and other accidents. I stop and tell myself to focus on what I am supposed to be doing. Ask yourself, what are you worrying about? Does anything you can do solve the problem? If you decide you can't do anything about the issue bothering you, then drop it. If you can fix the problem, then sit down and write down the problem and your solution. Best if you do this before the problem occurs, because worrying about a problem can often make it happen--self fulfilling prophesy!
