Don’t waste your life worrying. I know that is much easier said than done for most people.
To help you with this think of something in the past that you worried about and then think about it in the grand scheme of things. It didn’t really matter, did it?
If something happens to you that you can do something about then worrying makes no sense and if something happens that you cannot do anything about then worrying would not help you solve it, will it? What does that leave out? Nothing!
