Whatever you are worried about, I can almost guarantee that it won't matter in ten years. Maybe not even in 10 days or even 10 hours. Think back to a problem you had ten years ago. I bet it doesn't matter now. What's the use in worrying, it's really not worthwhile. All you end up doing is going from one worry to another. Most of which you will have forgotten about soon enough. If you find yourself moving from one worry to another, try re-framing them in you're mind as a challenge, or a chance to achieve success. This really is a more healthy approach.
