I didn't take your comments as criticism; I just feel very complementary toward you for what you have done with your worries. I don't believe any worries are worth thinking about because a worry is about something that hasn't happened, an imagined, possible future event and we cannot know the future and our imagination is notoriously limited in its ability to predict future events well.

The only "thinking" I think one should do about one's own worries is to identify them and then how to put them "at rest." Some can be ignored easily, using logical countering thoughts and others one has to figure out an action that will make their point moot, such as worrying about a co-worker so you decide to change jobs which takes that co-worker and worrying about them out of the picture.
